According to the program designing method of the first aspect of the invention, the hierarchical structure design means designs the processing units constituting the program using the hierarchical structure based on the related processing contents. Therefore, in the designed program, the characteristics of the processing contents become clear for each processing unit. In addition, by designing using a hierarchical structure, the structure of the program becomes easy to understand, and the relationship between the main processing and sub processing becomes clear. Further, the input / output design means sets a program component for performing input / output processing for each processing unit. Therefore, the program designer can easily perform the input / output design by using the program parts.

According to the second aspect of the invention, the processing design means designs the processing procedure and the processing contents for each processing unit designed by the hierarchical structure design means. Therefore, the program designer can design by paying attention to one processing unit, and can design more easily than designing the processing procedure and processing contents of the entire program at once.

【Example】

Example 1. An embodiment for realizing the program designing method according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a program designing method according to the present invention, and FIG. 2 is a flow chart showing a program designing procedure.

In FIG. 1, reference numeral 1 is a hierarchical structure design means for designing a processing unit of a target program by using a hierarchical structure. Reference numeral 2 is an input / output design means for setting program parts for input / output of screens, book tables, files, etc.
The set program components are stored in the input / output component storage unit 8. Reference numeral 3 is a processing design means, which is set with the setting of the processing procedure of the specific pattern used by the program, and the processing design unit 4 for designing the processing content for the processing unit using the set specific pattern. It is composed of five processing procedure storage units that store the processing procedure of the specific pattern. Reference numeral 6 denotes an input / output component design means, which is generated by the input / output component design unit 7 for designing program components for input / output, the input / output component storage unit 8 and, in particular, the program design method of the present invention. Existing program source 10
Extract program parts for input / output from a 11
And an input / output component extraction unit. Reference numeral 9 is a program source generation means for automatically generating the program source 10 based on the program information transmitted from the hierarchical structure design means 1.

Next, the operation of each unit and each unit shown in FIG. 1 will be described. The hierarchical structure design means 1 divides the program into processing units, and designs using the program hierarchical structure based on the divided processing units. The "program processing unit" here is a main routine and a subroutine or program library used in the main routine. The input / output design means 2 designs the input / output of the main routine and the subroutine, and the processing design means 3 designs the processing contents of the main routine and the subroutine.

The procedure of the above operation is illustrated in FIG. First, the program designer divides the program into processing units by the hierarchical structure design means 1 and structurally designs the program using a hierarchical structure based on the processing units (S1). Next, the input / output design (S
2) and processing design (S3) are repeated. Then, when the design of the program is completed (S4), the program source generation means 9 automatically develops it into the program source based on the program information designed in the above S1 to S3 (S5).

As described above, by designing the program using the hierarchical structure by the hierarchical structure design means 1, the target program becomes hierarchical and structural, and the program creator can easily grasp the entire program. , Program design productivity is improved.

The input / output design means 2 displays a screen for an arbitrary processing unit set by the hierarchical structure design means 1.
Set program parts for input / output of books, tables, etc. At this time, in this program design method, since the input / output component design means 6 is provided, it is possible to easily set the program components. For example, when setting a program component such as a screen, a book table, or a file that has already been designed, the program designer stores definition data without newly defining the format of the program component as described above. The program component can be set just by specifying the file name. Further, since the input / output component design means 6 is provided with the input / output component storage part 8, it is possible to display a list of the names of the files storing the definition data while the input / output design means 2 is operating. is there. Therefore, the program designer can easily set the program component by referring to this list display and selecting the program component to be used. Further, as described above, even when the corresponding program component is not stored in the input / output component storage unit 8, by using the input / output component design unit 7 included in the input / output component design unit 6, By selecting a similar program component from the component storage unit 8 and customizing it, the program component required by the program designer can be obtained. Furthermore, since the customized program component can be newly stored in the input / output component storage unit 8, it can be used without designing the customization operation again when designing another program. Further, since the input / output component design unit 7 can also refer to detailed component information of the program component stored in the input / output component storage unit 8, it is necessary to confirm the definition data before setting the program component. You can also

As described above, by providing the input / output component design means 6, the input / output component storage unit 8 and the input / output component design unit 7, it becomes easy to set the components for input / output, and the program design is produced. The property is improved. Further, the input / output component design unit 7 has a function of not only referring to detailed component information of the components stored in the input / output component storage unit 8 but also freely customizing, so that the degree of freedom in diversion of programs is improved. Therefore, the productivity of the program can be improved.

Next, the processing design means 3 sets, for an arbitrary processing unit set by the hierarchical structure design means 1, a processing procedure which is an operation logic of the processing unit. As for the procedure to be set, the processing design means 3 includes the processing procedure storage unit 5, so that the processing procedure of the specific pattern can be prepared and stored in the processing procedure storage unit 5 in advance. Therefore, it is possible to easily set the processing procedure by referring to the processing procedure storage unit 5 by the processing designing unit 4 included in the processing designing unit 3 and selecting the corresponding processing procedure.

FIG. 3 shows an example of the processing procedure of the specific pattern stored in the processing procedure storage unit 5. A processing procedure storage unit 5 stores processing procedures such as a screen flow 51 and a book table flow 52. Here, 53 is an arbitrary processing flow, and the processing procedure storage unit 5 can store a plurality of arbitrary processing flows. Reference numeral 54 is a processing block forming the processing flow 53.

As shown in FIG. 3, a processing flow corresponding to each processing such as a screen, a table, and a file is prepared in advance in the processing procedure storage unit 5, so that a program for assembling the blocks constituting the processing is created. Since it is only necessary for a person to do so, the productivity of program design can be improved when a new program is designed.

Further, the process designing section 4 of the process designing means 3 can refer to detailed information of the program parts for input / output used by the program by using the input / output part designing section 7. Therefore, the design of the processing content to be performed for each processing block can be performed with reference to the detailed component information stored in the input / output component storage unit 8, so that the design can be performed accurately and the productivity of the program design is improved. To do.

Further, the program source generation means 9 inputs the program information designed by the hierarchical structure design means 1 and automatically generates a program source based on the designed contents. The automatically generated program is stored in the program source 10. Further, depending on the program description language, it has to be compiled into a computer-executable format. Therefore, the program source generation means 9 can further compile the generated program source to automatically generate an executable program. is there.

Further, the input / output component extraction unit 11 extracts the program components for input / output from the program source 10 and the existing program source 10a including the existing program source not according to the present invention, and the input / output component storage unit. Store in 8. As a result, the existing program resources created in the past can be diverted to design the program, and the productivity of the program can be improved.

As described above, according to the program designing method of the present invention, the hierarchical structure designing means 1 causes the main routine and subroutines used in the target program,
A processing unit such as a library is set, and a hierarchical structure of the program is designed. Then, the input / output design means 2 refers to the input / output component storage unit 8 to set the program components for input / output. Further, the processing procedure to be used is set by referring to the processing procedure of the specific pattern stored in the processing procedure storage unit 5 by the processing design unit 4 for each processing unit of the program and selecting the corresponding processing procedure, The processing content can be designed for each processing block. The program information created by the above operation is automatically converted into a program source by the program source automatic generation means 9.

Further, the parts stored in the input / output parts storage part 8 can be referred to and customized by the input / output parts design part 7. The input / output component design unit 7
It can be activated by the input / output design means 2 and the processing design unit 4.

Further, the input / output component extraction unit 11 can extract the program components for input / output from the existing program source.

Example 2. In the above-described first embodiment, the configuration of the program design method according to the present invention has been described. In this embodiment, a case where a program is actually designed based on the program design method described in the first embodiment will be described below using a specific example.

First, the specifications of the program to be designed will be described. FIG. 4 is a diagram for explaining the input / output file organization of the program. FIG. 5 is a diagram for explaining the processing contents of the program. FIG. 6 is a diagram for explaining the processing contents of the program following FIG.

The program to be designed from now on is a program for inputting a sales slip in the sales management system. According to FIG. 4, the program name is "DEN001", and the outline of the processing of this program is to input data from the workstation (WS) based on the sales memo, update the stock number of the product master file, and to update the sales log file. Export sales information to.
Since the sales slip is managed for each customer, the customer code is input prior to the data input, and it is confirmed whether or not the corresponding code exists in the customer master. Furthermore, "DEN0
The configuration of the file used in "01" is input of a sales slip from the screen, input of a customer master file, output of a sales log file, and update of a product master file. Next, looking at the detailed processing contents according to FIGS. 5 and 6,
This program includes "initial processing (IN)", "heading processing (HD)", "detailed processing (DT)", and "total processing (T)".
L) ”and“ terminal termination processing (TE) ”, and
It consists of "standard error handling" (external subroutine).

Further, the processing contents of FIGS. 5 and 6 are shown in a flow chart of FIG. According to FIG. 7, first, a password input process and a work screen display process are performed (IN) in order to start the sales slip input program as the “initial process”. Next, the customer code input processing is performed as "heading processing", and at the same time, the business end determination is performed based on the input value of the customer code (HD). Next is "detailed processing", which is composed of "one-line detailed processing (DT1)", "one-line end processing (DE)", and "one-line correction processing (DC)". In the "one-line detail processing", product code input processing and detail line input processing are performed. In the product code input process, the specification line end determination is simultaneously performed based on the input value of the product code.
In the “one-line end process”, the product master file update process and the log file output process are performed. This "one-line end process" is executed when the entered detail line is confirmed.
The "one-line correction process" is a process of clearing the detail line to be corrected. This "one-line correction process" is executed before the entered detail line is confirmed. When the end of the detail line is determined by the "one-line detail process", the "total process" is performed. "Total processing"
Then, the total display processing of the sales amount is performed. After the "total processing" is completed, the processing is repeated again from the "heading processing".
When the end of the work is determined by the "heading process", the "terminal end process" is performed. In the "terminal termination process", a termination screen display process is performed.

The above "initial processing" to "terminal end processing"
Since this is a screen-related process, this is the main routine. However, since the "one-line end process" of the "detailed process" is a file-related process, a subroutine is executed. Although not shown in FIG. 7, “standard error processing” is shown in FIG.
Is described. In general, error handling is commonly used in all programs, so "standard error handling" is also used as an external subroutine in this program. FIG. 8 shows the relationship between the main routine and the subroutine and the relationship between the processing blocks using a hierarchical structure. According to FIG. 8, the sales slip input main processing is composed of processing blocks of “initial processing”, “heading processing”, “details processing”, “total processing”, and “terminal end processing”. Furthermore, "detailed processing" means "one-line detailed processing",
It is composed of "one-line end process", "one-line correction process", and "standard error process". Also, "standard error processing" exists as an external subroutine in parallel with the main processing. As explained above, the "single line end process" is
This subroutine is activated by "detailed processing", and is composed of four processing blocks: "initial processing", "product master update", "log file output", and "end processing".

Next, "initial processing", "heading processing",
The processing procedure of “one-line detail processing”, “one-line end processing”, “one-line correction processing”, “total processing”, and “terminal end processing” will be described with reference to FIGS. 9 to 14. FIG. 9 is a diagram for explaining the processing procedure of the “initial processing (IN)”. In the "initial processing", the password is input (S10) and the work screen is displayed (S11). When the "initial processing" is completed, the control is transferred to "heading processing (HD)". FIG. 10 is a diagram illustrating the processing procedure of the “headline processing (HD)”. In the "headline processing", the customer code is input (S1
2) If the input customer code is '999' (S13), the "heading process" is terminated and the control is transferred to the "terminal termination process (TE)". In the determination process of S13, if the customer code is other than "999", it is checked whether the input customer code exists in the customer master file (S14). In the process of S14, if the customer code does not exist in the customer master file, the external subroutine is activated to perform "standard error processing". In the process of S14,
If the entered customer code exists in the customer master file, obtain the customer name from the corresponding record,
The customer name is displayed on the screen (S15). Next, in order to initialize the total amount calculation area, "0" is set (S16). Then, in order to newly input the statement, the statement input screen is erased once and displayed again (S17). When the "heading process" is completed, the control is shifted to the "details process (DT)".

FIG. 11 is a diagram showing a processing procedure of "one-line detail processing (DT1)" which is one of "detailed processing (DT)". In the "one-line detail processing", first, the product code is input (S18). The entered product code is'
If it is 9999 '(S19), "total processing (T

0), the detail entry screen is erased once and displayed again (S
21). The product master file is searched (S22), and if the corresponding product code does not exist, the external subroutine of "standard error processing" is activated. In the process of S22, when the corresponding record exists, the product name and unit price are acquired and displayed on the screen (S23). Then, the sales quantity of the product is input from the screen (S24).
The sales amount is calculated based on the unit price and the quantity acquired in S23 and S24 (S25), and the calculated amount is displayed on the screen (S26). The processing from S18 to S26 is the processing relating to each detail line, but when the input value is changed (S27), the control is shifted to the "one-row correction processing (DC)". If there is no correction, "One line end processing (D
Control is transferred to the subroutine "E)".

FIG. 12A shows "one-line correction processing (D
8 is a flowchart showing a processing procedure of "E)". In the "single-line correction process", the detailed line with the correction is erased (S28), and the control is transferred to the "single-line detailed process (DT1)".

FIG. 12B shows "one line end processing (D
10 is a flowchart showing a processing procedure of "E)". The "one-line end processing (DE)" is a subroutine for updating a file as described above. This subroutine is activated by the "one-line detail processing (DT1)" described above. After the activation, the file update process is performed, and the process returns to the "one-line detail process (DT1)". In the "one-line end process (DE)", first, the inventory quantity is calculated (S29). The stock quantity is calculated by subtracting the quantity input in S24 from the stock quantity in the product master record acquired in S22 to obtain the current stock quantity. The process of S29 corresponds to the "initial process" that constitutes the "one-line end process" of FIG. When the calculation of the inventory quantity is completed, the above-mentioned S22 is performed based on the calculated inventory quantity.
The product master record input in step S30 is updated (S30).
The process of S30 corresponds to the "product master update" that constitutes the "one-line end process" of FIG. Furthermore, the sales information is output to the sales log file, with each detail line as sales for one case (S31). The process of S31 corresponds to the "log file output" that constitutes the "one line end process" of FIG. When the file update is completed, the amount calculated in S25 is added to the total amount to obtain a new total amount (S3).
2). The process of S32 corresponds to the "end process" that constitutes the "one-line end process". "One-line end processing (DE)"
When is completed, control is transferred to "one-line detail processing (DT1)".

FIG. 13 is a flowchart showing the processing procedure of the "total processing (TL)". "Total processing (TL)" displays the total amount of money calculated in S32 on the screen (S3

The name of the program that has already been set is displayed. Input file 116b, reference file 116c, output file 1
16d and the update file 116e are displayed by default when the I / O selection (I) on the program design screen 100 of FIG. 15 is selected. Therefore, the input file, reference file, output file, and update file used in the program are set as necessary. For example, in the case of a program in which an update file does not exist, it is determined that there is no update file unless a file name is specified in the update file specification frame 116i. Output file is 2
In such a case, if two file names are specified in the output file specification frame 116h (according to FIG. 25, the output file has two items, “sales log file” and “sales list”).
It is determined that two types of files exist as output files.

FIG. 26 is a diagram showing an example of displaying a file list in which definitions of input / output information are stored. The screen list 117 is a screen displayed when the list (M) of the program design screen 116 is selected. File List 117

FIG. 28 shows a display example when “sales log file” and “commodity master file” are selected.

FIG. 29 is a flow chart showing the procedure of program design and input / output design. Next, using the diagrams of FIGS. 15 to 28, according to the flowchart of FIG. 29, the hierarchical structure design means 1,
The input / output design means 2 and the input / output component design means 6 will be described. First, set the program name. For setting the program name, there is a menu screen (not shown) before displaying the program design screen 100 of FIG. When selecting the program design from the menu screen (not shown), the program name is designated. As described above, in this embodiment, since the program of the sales slip input “DEN001” is designed, the program name is designated as “DEN001” (S40). When the program name is designated and the program design is selected, the program design screen 100 of FIG. 15 is displayed. The hierarchical structure displayed on the program design screen 100 of FIG. 15 is a hierarchical structure set as an initial value, the processing unit 100a represents a main routine, and the processing units 100c to 100h represent a part of the main routine. The processing unit of the lower hierarchy which comprises is shown. Processing unit 1
00b is a subroutine commonly used in the system. Therefore, the program designer performs the design while considering the hierarchy of the processing unit of the program to be designed.

For example, the "DEN00 described above.
According to FIG. 8, the program "1" is composed of a main routine for inputting a sales slip, one subroutine for updating files included in the main routine, and one external subroutine for performing standard error processing. This structure is designed using the hierarchical structure design means 1. First, the main routine is set, but the information name of the main routine is the same as the program name set in S40. Therefore, the information name is already displayed as "DEN001" in the processing unit 100a of FIG. Has been done. Therefore, the designation of the program information name of the main routine (S41) is omitted. Next, the program specifications of the main routine are set. The program specification is set on the program specification setting screen 102 shown in FIG. According to FIG. 16, the program specification is composed of three program names 102a, types 102b, and parameter specifications 102c. Since the program name of the main routine is "sales slip input", "sales slip input" is designated as the program name 102a. Since the type 102b is the main routine, “main” is selected from the type options 102e. Also,
Since this program has a hierarchical structure, the hierarchy is selected.
Furthermore, since it is a unique program for inputting a sales slip in the system, "unique" is selected. Since the main routine is not started by another program, the setting of the parameter specification 102c is omitted (S42).

Next, the program specifications of the subroutine for updating the file are set. Since the file update subroutine is a subroutine forming a part of the sales slip input main processing, this subroutine is set in the processing unit 100c. First, specify the program information name (S
41). The designation of the program information name is displayed when the hierarchy (K) on the program design screen 100 is selected. FIG.
Further selection of design target from the work option 200b (L)
Select, you can set. The information name “SUB00” is displayed in the information name 109a of the program name input screen 109.
It can be set by inputting "1" and clicking the design button 109b. The set information name is displayed in the processing unit 100c of the program design screen 100.

Next, the program specifications are set (S4
2). Since the name of the subroutine "SUB001" is "file update", "file update" is set in the program name 102a. For the type 102b, a sub is selected from the type options 102e and set. Also, because this subroutine is part of a hierarchical structure and can be expected not to be used by other programs, "hierarchical"
And select "unique". Also, when starting the file update subroutine from the main routine for entering sales slips,
Since the parameter is not necessary, the parameter specification 102c is not set.

Finally, an external subroutine for standard error processing is set. The standard error processing is an external subroutine that is also used in programs other than the "DEN001" program, so the specifications have already been determined, but it is assumed in this embodiment that the standard error processing program specifications have not been set yet. And make the settings. The information name of the standard error process is “ERR001” and is set in the information name 109a of FIG. After setting, when the setting button of 109b is clicked, "ERR001" is displayed in the processing unit 100d of the program design screen 100. Further, in the setting of the program specifications of the standard error processing, "standard error processing" is set in the program name 102a, and non-resident sub is set in the type 102b. Since the standard error processing is a routine that is required only when an error occurs, it is not necessary to always exist in the main memory, so the non-resident sub is selected from the type selection 102e. In addition, standard error handling is part of the hierarchical structure in the sales slip entry program, but it may also be started from other programs, and there are cases where it does not have a hierarchical structure, so "simple" and "common" Select. In the parameter specification 102c, an error code specification necessary for starting the standard error processing routine is set. The parameters are set on the parameter setting screen 103h shown in FIG. Since the parameter specifications of the standard error processing are as shown in FIG. 6, "Error code" is set for the name 103c and "for the type 103d".
9'is set and the length 103e is set to '10'.
The content set in the description 103f is arbitrary, and thus may be set as necessary.

In this embodiment, "USING parameter" is set as shown in FIG. When the setting button 103g is clicked after the setting is completed, the names are displayed as many as the number of parameters set as "error code" in the parameter 103a of FIG. 18 (A).

In this embodiment, the program specification of the external subroutine "standard error processing" is set again as described above. However, when the program specification has already been set, the set program specification is set as shown in FIG. Processing unit 1
It is also possible to set the name of the file in which the program specification of "standard error processing" is stored in the common reference of 00b. This method is performed by selecting the list (M) of FIG. 15 and selecting the external subroutine (O) of the work option 200d of FIG. 24, which is displayed, and selecting “standard error processing” of “J7C025” from the program list 113a displayed. Move the cursor to and click the design button 113b.
"Standard error processing" in common reference of processing unit 100b of 5
Is displayed, and it is possible to declare the use of "standard error handling" in the sales slip input program. This completes the setting of the processing unit in the sales slip input program (S43).

After setting the program specifications for all the processing units, the program outline is set (S44).
The processing outline of the sales slip input program is as shown in FIG. The program outline can be set from the work option 200a displayed by selecting the program (P) on the program design screen 100 of FIG. 15 and from the program design outline setting screen 104 displayed by selecting the program outline (G). Yes (Fig. 19). The process outline shown in FIG. 4 is input to the program outline 104a of FIG. 19 from the keyboard, and the setting button 104b is entered.
Click to set the entered program summary. The steps S40 to S44 described so far are the processes performed by the hierarchical structure design means 1.

Next, the setting of the input / output of the program in the input / output design means 2 and the input / output component design means 6 will be described. First, input / output information is set from the program design screen 116 displayed in FIG. 25 (S4
5). The program design screen 116 of FIG. 25 is a screen displayed when I / O selection (I) is selected from the program design screen 100 of FIG. The program design screen 116 is a screen display example after the input / output information is set. In FIG. 25, four files 116b to 116e are displayed (the program name is displayed on 116a). Four of these files are displayed by default regardless of the program to be designed. Information related to input is set in the input file 116b. As the setting method, the input file name is designated in the input file designation frame 116f. In the reference file 116c,
Set input / output information for reference. Furthermore, output information is set in the output file 116d, and update information is set in the update file 116e. For example, there may be a case where there is no file referred to by the program to be designed. In this case, unless the reference file name is specified in the reference file specification frame 116g, it is determined that the file input / output related to the reference is not performed. In addition, depending on the program, there may be multiple files to be output. For example, if the output files are the sales log file and the sales list, it is determined that two output files exist by specifying the sales log file and the sales list in the output file specification frame 116h.

Next, a method of designating a file name in the file designation frame will be described. File specification frame 116f
A plurality of file names can be designated for .about.116i. This is because the file designation frames 116f to 116i are composed of a plurality of lines. The program designer moves the cursor to the line for inputting the file name, and when the cursor is clicked after the movement, the file name can be input in that line, so the file name is directly input from the keyboard. Also, by selecting the list (M), the file list 11 as shown in FIG.
It is also possible to display 7a, select the corresponding file from this list, and specify the file name. If the file names are classified in advance into screen-related, book table-related, etc. by extension, only the related files can be displayed in the file list of FIG. 26 by the program designer designating the file type. This allows the program designer to easily find and set the file name to use.

When selecting a file name, it is possible to confirm the defined file information before selecting. This is supported by the input / output component design means 6 in FIG. To check, move the cursor to the file you want to check from the file list 117a in FIG. 26, click once to confirm the file, and design button 117b at the bottom left of the screen.
Click. For example, when the screen for entering the sales slip is selected, as shown in FIG. 27, a screen image 11 for entering the sales slip is displayed.
8 can be referred to. Further, when the sales log file is selected, the format definition 119a of the sales log file can be referred to as shown in FIG. Furthermore, when it is desired to change the definition information of the referenced file,
And, new file definition information can be created by directly inputting the change information on the screen of FIG. The method of changing the definition information will be described in detail in a later embodiment. The above is the method of setting the input / output information by the input / output design means 2 and the input / output component design means 6 in FIG.
The setting of the input / output information in S45 is repeated until the setting is completed for all the input / output files used in the designed program (S46).

When the setting of the input / output information is completed, the process design is set (S47), but the process design will be described in detail in the third and subsequent embodiments, and will not be described in this embodiment. When the processing design setting is completed, the information of the set program is registered (S48). Program information registration,
This is done on the program registration screen 105 of FIG. This screen is a screen displayed when the program (P) is selected from the program design screen 100 of FIG. 15 and the registration (P) is selected from the displayed work options 200a. On the program registration screen 105, it is possible to change the program name and the program name specified in S40 and S42. If you want to change the program name and program name after the change
It is possible to register a program designed with a new name by inputting each in a and the program name 105b and clicking the registration button 105d.
When the registration button 105d is clicked, if the program information to be registered already exists, the program design screen 106 is displayed to protect the program information. Further, in the case where the design is continued after the program information is registered, it is possible to return to the program design screen 100 of FIG. 15 again by designating "Continue design". When continuing the design, the program design screen 107
The confirmation screen is displayed, and it is possible to select whether to register the program information or not before switching to the design screen. Further, when the program information is changed and the program is terminated without being registered (FIG. 21), the program design screen 108 may be selected to register the program information or not before the program information is finished. Can be performed (S49).

As described above, the hierarchical structure design means 1, the input / output design means 2, and the input / output component design means 6 can interactively set the program structure, the input / output files, etc. on the screen, so that the program designer can design the design sheet. You can design a program more efficiently than writing your own design contents in. Also, it is possible to set the use of subroutines and file definition information that are commonly used in the system by specifying the program name and file name without designing a new one if it has already been designed. it can. Further, the set file definition can be changed by the program designer to any definition content as necessary and registered as new file definition information. As a result, it is possible to easily use the existing program components rather than designing them all newly, and it is possible to easily improve the program design efficiency.

FIG. 56 is a flowchart showing the processing procedure of block design. FIG. 57 is a flowchart showing the processing procedure of the detailed design.

Next, the design of the processing contents by the processing design means 3, the processing design unit 4, and the processing procedure storage unit 5 will be described with reference to FIGS.
The following description will be given with reference to FIG. 53 and the flow charts of FIGS. According to FIG. 54, the design performed by the processing design means 3 is composed of three stages of design. The processing content is designed for each processing unit using the hierarchical structure designed in the second embodiment. First, module design is performed (S50). Modular design determines the module type. Since the processing procedure is determined when the module type is determined, the processing content is divided into processing blocks according to the processing procedure. Block design is performed for each of the divided processing blocks (S51). In the block design, one processing block is divided into pre-processing, main processing, post-processing, etc., and the processing content is determined for each processing. The design of the processing contents in the block design is not the detailed design for each step of the program, but the design of the main processing.

Next, detailed design is performed for each processing content designed in the block design of S51 (S52). In the detailed design, detailed processing contents corresponding to one step of the program are set. For all processing units, the module design of S50 to the detailed design of S52 are repeated until the process design is completed (S53). When the design is completed for all the processing units, the designed program information after S48 in FIG. 29 is registered and the design is completed.

Next, the processing procedure in module design will be described below with reference to the flowchart of FIG. To design a module, first, on the program design screen 100 of FIG. 15, one processing unit to be designed is selected. For example, the program design screen 100
When a module design for inputting a sales slip (processing unit 100a) is performed, the cursor is moved to the processing unit 100a and clicked to make a selection, and the module design (F) is selected. As a result, the module design of the processing unit for inputting the sales slip can be performed thereafter.

Next, the module type of the selected processing unit is selected (S61). The module type setting screen 120 of FIG. 30 has already been displayed on the screen by selecting the module design (F) in the process of S60. From the module type display screen 120a, the module type corresponding to the processing unit for which module design is to be performed is selected. The processing unit for inputting the sales slip selected in S60 is processing for inputting the sales slip from the workstation and displaying the sales amount on the workstation based on the quantity of the product input from the sales slip. Therefore, the module type is "screen". Select "Screen" on the module type display screen 120a and click the setting button 120b. When the setting button 120b is clicked, the module design screen 121 of FIG. 31 is displayed (S62). Module design screen 1
From 21, it is not possible to directly set the processing contents. In order to set the processing contents, first, the cursor is moved to the first line of the module design screen 121 and clicked to select the line for displaying the designed contents, and further select the module (D) (S63). . Module (D)
When is selected, the work option 200f of FIG. 32 is displayed. When the processing content (P) is selected from the work options 200f, the processing content setting screen 122 is displayed. The processing content is set on the processing content setting screen 122 (S64). Prior to setting the processing content, the processing flow of the module type "screen" selected in S61 is confirmed, and the name of the section to be designed is referred to. To refer to the processing flow of the module type “screen”, the tool (T) on the module design screen 121 of FIG. 31 is selected. When the tool (T) is selected, the work option 200g shown in FIG. 33 is displayed. Therefore, the screen (G) is selected from the work options 200g. As a result, FIG. 34 (A)
The screen processing flow display screen 124 is displayed.

The processing unit for inputting sales slips designed in this embodiment is composed of five processing blocks, which are initial processing, heading processing, detailed processing, total processing, and terminal termination processing, as shown in FIG. When this processing block is compared with the screen processing flow display screen 124 of FIG. 34A, the initial processing corresponds to the initial processing 124a, the heading processing corresponds to the heading processing 124c, and the detailed processing corresponds to the detailed processing 124d.
And the total processing corresponds to the statement end processing 124e,
It can be seen that the terminal termination process corresponds to the termination process 124g. Since the first design is the initial processing,
Area 1 for inputting categories of the processing content setting screen 122 of FIG.
22. "Initial processing" is input to 22a. Part name 12
In 2b, the program component name used in the initial processing is specified. According to FIG. 9, in the initial processing, the work screen is displayed. The work screen to be displayed has definition data stored in the work screen text. Therefore, the part name designation area 12
In 2b, "work screen text" is designated. In the processing condition designation area 122c, conditions for displaying the work screen text are designated. According to the flowchart of FIG. 9, the work screen is displayed when the password input check is OK (S10
a), the display is made. For this reason, "when the password check is OK, the work screen is displayed" is designated. The comment input area 122d can be arbitrarily input by the program designer.

As described above, the processing content is set using the processing content setting screen 122 (S65). When the setting button 122e is clicked after setting the processing content, the processing content set in S65 is displayed on the module design screen 121. However, the processing conditions and comments are not displayed on the module design screen 121. As can be seen from the display result, the processing category 121a displays the value input in the category input area 122a, and the component name 121b displays the value input in the component name input area 122b (S66). ).

The process from S63 to S66 is the setting of one processing block. In addition to the initial processing, the processing unit for inputting the sales slips includes the heading processing, the detail processing, the total processing, and the terminal termination processing. Then, the contents set on and after the second line of the module design screen 121 are displayed. When the processing contents have been set for all processing blocks (S67), block design is performed next.

When setting the processing contents in S65, when inputting the classification name in the classification input area 122a of FIG. 32, and when the screen processing flow display screen 124 of FIG. 34 (A) is displayed, 124a By selecting the process desired to be input with the cursor from among ~ 124g, the program designer can automatically input without using the keyboard. For example, if "initial processing" is entered in the area 122a for division input as described above, the initial processing 12 of the screen processing flow 124
If the cursor is moved to 4a and is clicked, it is automatically input to the division input area 122a.

Next, the processing procedure for block design will be described below with reference to the flowchart of FIG. First of all,
A processing block to be designed is selected (S71).
The processing block is selected by the module design screen 1 shown in FIG.
Select the processing block to be set by moving the cursor from the processing categories displayed in 21 to the processing category for which block design is to be performed, clicking this, and further selecting block design (B). it can. For example, from the module design screen 121 of FIG. 31, when the category “headline processing”, “part name”, and “headline text” are selected and block design (B) is selected (S72), the block design screen of FIG. 38 is displayed. 129 is displayed (S7
3). On the block design screen 129, the contents of the block design cannot be set. To set the details of the block design, the processing content setting screen 130 of FIG. 39 is displayed, and the processing content is set using this screen. To display the processing content setting screen 130, one line for displaying the processing content set in advance on the block design screen 129 is selected. For example, when the cursor is moved to the first line of the block design screen 129 and then clicked and then the block (B) is selected, the work option 200e in FIG. 39 is displayed.
When the processing content (P) is selected from the work options 200e, the processing content setting screen 130 is displayed (S75). The processing content of the block design is set on the processing content setting screen 130.

First, a category name is entered in the process category input area 130a. When the division name is input, the tool (T) on the block design screen 129 is selected, and the processing division (P) is selected from the work options 200h shown in FIG. 40, the processing division display screen 131 is displayed. . The classification name displayed on the processing classification display screen 131 is designated in the processing classification input area 130a. Although the program designer can directly input the designation from the keyboard, when the cursor is moved to and clicked on the corresponding process category from 131a to 131c on the process category display screen 131, the category is divided into the process category input area 130a. You can enter the name. Here, "preprocessing" is input in the processing category input area 130a. In the processing content setting area 130b, the processing name which is the center of the processing in the "preprocessing" is input. Here, since the display of the headline text 2 is the center of the process, "headline text 2" is input. The condition specification area 130c includes a processing content setting area 130b.
If there is an execution restriction in the processing contents entered in, set the condition to restrict the execution. Since there is no condition for restricting the execution of the processing of the headline text 2, no condition is input. The program designer can arbitrarily input a comment in the comment input area 130d. However, the contents input in the condition designation area 130c and the comment input area 130d are not displayed on the block design screen 129.

As described above, after setting the processing contents (S76) and clicking the setting button 130e, the processing contents set in the above S76 are displayed on the block design screen 129 (S77). Above S74-S7
The processes up to 7 are repeated until the setting is completed for all the process categories of the selected process block (S7).
8). For example, the headline processing includes main processing and post-processing in addition to preprocessing. Therefore, when the processing contents of the main processing and the post-processing are set according to the steps S74 to S77, as shown in the block design screen 129,
It can be seen that the customer code is mainly input in the main processing, and the customer name is mainly output in the post processing. After the setting of the processing content of the selected processing block is completed (S7
8) Since there are other processing blocks in the processing unit for inputting the sales slip, all the remaining processing blocks must be designed according to the procedure from S71 to S77. When the design is completed for all the processing blocks of the processing unit for inputting the sales slip (S7
9) Next, detailed design is performed.

Next, the processing procedure of the detailed design will be described below with reference to the flowchart of FIG. In order to perform the detailed design, first, one processing category to be detailed designed is selected from the processing categories 121a displayed on the module design screen 121 of FIG. As for the selection method, for example, in the case of selecting “heading processing, heading text 2”, the cursor is moved to the third line of the module design screen 121 and clicked, and then the block design (B) is selected (S8).
1). When the block design (B) is selected, the block design screen 129 of FIG. 38 is displayed. Block design screen 1
Since the processing content of "heading processing, heading text 2" is displayed in 29, the processing category for which detailed design is performed is further selected. For selecting the processing category, for example, when selecting "main processing, customer code", move the cursor to the second line of the block design screen 129 and click (S8).
2) Further, the detailed design (S) is selected (S83). When the detailed design (S) is selected, the detailed design screen 13 in FIG. 41 is displayed.
2 is displayed (S84). After the detailed design screen 132 is displayed, a process outline is first input from the terminal to the process outline designation area 132a. In this embodiment, since the detailed design of the main process is performed, the process outline is “input customer code” (S85).

Next, a detailed design is carried out. Detailed design screen 1
No. 32 cannot directly set the processing content. The processing content is set on the processing content setting screen 133 of FIG. In order to display the processing content setting screen 133, one line for displaying the processing content set on the detailed design screen 132 is selected, and the detail (S) is selected from the work options 200i of FIG. 42 displayed. , Processing content (S)
Is displayed when is selected. For example, the detailed design screen 132
When it is desired to display the contents to be designed on the first line of, the cursor is moved to the first line of the detailed design screen 132 and clicked, and the detail (S) is selected (S86). Then, when the processing content (S) is selected from the displayed work options 200i, the processing content setting screen 133 is displayed (S87), and the processing content is set from this design screen. In setting the processing content, first, the location name is input from the terminal to the location name input area 133a.
In the main process, the customer code is input, and the input is repeated until the input customer code exists in the customer master file. Therefore, the location name is named re-input. The condition specification area 133b is the processing content input area 133c.
If there is a condition that restricts the execution of the process set in, enter the condition. Next, the processing content is set in the processing content input area 133c. According to the flowchart of FIG. 10, the customer code is first input (S12). When this is set in the processing content input area 133c, it becomes a "terminal input customer code". Looking at the flow chart of FIG. 10, since there is no condition for restricting the processing for the input of the customer code, no condition is set in the condition designation area 133d. The program designer can arbitrarily set a comment in the comment input area 133d. Here, a comment is set that "Enter the customer code from the terminal". When the setting button 133e is clicked after the setting of the processing content is completed (S88), the set processing content is displayed on the detailed design screen 132 of FIG. 41 (S89). Since there are still other processing contents in the main processing, the above S86 to S
The processes up to 89 are repeated. The result of repeated execution is displayed on the detailed design screen 132. Detailed design screen 1
"Customer code = '999'" in the third line of 32
This is the content set in the condition designation area 133b. This condition was set as a condition for limiting the branching process of "branching to the end process".

In order to more easily set the processing contents described above, when the tool (T) on the detailed design screen 132 is selected, the processing parts of the program as shown in FIGS. Is prepared, the program designer can easily set the processing contents by using these program processing parts as needed. For example, when the condition displayed on the third line of the detailed design screen 132 of FIG. 41 is input, from the work options 200j of FIG. 43 displayed when the tool (T) of the detailed design screen 132 is selected. , "Comparison" of the general instruction is selected from the processing instruction menu screen 164 displayed by selecting the processing content (S). When "Compare" is selected, the comparison command setting screen 135 of FIG. 44B is displayed. When conditions are set using this screen, "customer code" is specified for item name 1 135a, "=" is set for comparison command 135b, and "'99 is set for item name 2 135c.
9 '"is set. Further, "Y" is set in the comparison result 135d to set the comparison result when branching the process, and "end processing" is set in the destination 135e. By setting in this way, the program designer can easily perform detailed design. In addition to the program parts for comparison instructions, there are processing parts that are also available.

A setting screen for calculation is introduced in FIG. 44 (A). In addition, a setting screen for transfer is introduced in FIG. Further, FIG. 45 (A) shows a setting screen for totalizing the table, FIG. 45 (B) shows a setting screen for sorting the table, FIG. 46 (A) shows a setting screen for table search, and FIG. 47 (B) is a screen for setting a comment, FIG. 47 (A) is a screen for setting an open / close command regarding a file, FIG. 47 (B) is a setting screen for file input (sequential), and FIG. ) Has a setting screen for file input (random). FIG. 48
In FIG. 48A, a record output process setting screen for files is prepared, and in FIG. 48B, a record update setting screen is prepared. In FIG. 49, a setting screen for deleting records is prepared. 44 to FIG.
Up to FIG. 49, the instructions are general instructions and instructions relating to files. From FIG. 50 onward, processing parts of the program relating to the screen and the book table are introduced.

In order to display the processing command menu screen 147 of FIG. 50, "screen" is selected from the processing classification of FIG. 43 and is displayed. The processing parts related to the screen are shown in FIG.
An open / close command setting screen is introduced in (A), a terminal input / output setting screen is introduced in FIG. 51 (B), and a function lamp setting screen is introduced in FIG. 51 (C). There is. Further, FIG. 52A shows an error display design screen, FIG. 52B shows a screen clear process setting screen, and FIG. 52C shows a screen clear process setting screen. . Furthermore, FIG. 53 introduces commands related to book table output. FIG. 53 (A) shows a setting screen for setting open / close processing, and FIG. 53 (B).
In FIG. 53, a setting screen for book table output and a setting screen for special control processing are introduced in FIG. For example, in the fourth line of the detailed design screen 132, there is a process of randomly inputting the customer master file with the customer code as the key. If the customer code does not exist, branch to standard error processing. Has been done. Here, "Sign 99"
This is because, in the random input setting of the file in FIG. 47C, when the input result is invalid, the indicator is set to '99'. is there.

The setting of the processing contents of S82 to S89 described above is performed by designing the selected processing section (S9).
0) and all the process divisions forming the selected process block, the setting process is repeated until the design is completed (S91). When the detailed design is completed for all the processing divisions forming the processing block, the above S81 to S8 are performed.
The processing up to 9 is repeated until the design is completed for all the processing blocks forming one processing unit (S
92). When the design is completed for all the processing blocks, the process proceeds to the branching process of S53 in FIG. 54, and the module design and block design from the revised S51 to S52 are performed until the design of the process is completed for all the processing units that make up the program. , Repeat the detailed design. The process flow described in this embodiment refers to the process flow stored in the process procedure storage unit of FIG.

As described above, the program designer can interactively design a program according to the program design menu displayed on the screen by the processing design means 3, the processing design unit 4, and the processing procedure storage unit 5. The efficiency of designing a program can be improved. Further, the program is divided into parts by preparing a processing flow and a large number of processing parts of the program, and the program can be designed at a certain level without being influenced by the technical level of the program designer.

Example 4. When performing the detailed design of the program described in the third embodiment, when the processing contents are set by using the input / output component design unit 7, screen definition information and file definition information are displayed on the same screen. Can be displayed and referenced. For reference, first, the tool (T) on the detailed design screen 132 of FIG. 41 is selected and the file to be referred to is selected from the work options 200j displayed. For example, since there is a “product master file” in the work option 200j of FIG. 58,
When this is selected, the detailed design screen 132 of FIG. 41 is displayed above the product master definition file 157c. For example, when the program designer is setting the processing contents of "one-line detail processing", according to the flowchart of FIG. Item master definition file 157c when checking how many digits should be used
The number of digits of the unit price can be found by referring to. According to the product master definition file 157c, the number of digits of the unit price is five, and if the number of digits of the quantity is known, the number of digits of the amount of money can be determined. Since the quantity is input from the sales slip, when the sales slip input is further selected from the work options 200j, the sales slip input screen image 118 is displayed as shown in FIG. Since it can be determined from this screen that the quantity is 6 digits, it can be determined that the calculation can be performed if the maximum amount of 11 digits is prepared.

As described above, since the definition information of a file can be displayed on the same screen during the process setting of the file definition information by the input / output component designing unit 7, the program designer can save the file in the conventional manner. It is possible to design a program while checking definition information of a file in real time without carrying the definition material to the design location.

Example 5. In this embodiment, an example of editing the definition information of the file by the input / output component design unit 7 of FIG. 1 will be described below.

FIG. 59 is a diagram showing an example of deleting a part of the definition information of a file. FIG. 60 is a diagram showing an example of newly adding definition information to a part of the definition information of a file. 61 is a diagram showing definition information of a new file as a result of the process of newly adding another definition information to the definition information of the file of FIG. 60.

First, an example of deleting a part of file definition information will be described. File design screen 15 of FIG. 59
8 displays the file design screen 119 shown in FIG. 28 described in the second embodiment in the same procedure as that shown in FIG. 28. Therefore, in this embodiment, the description of the display procedure will be omitted. For example, if the sales log file is displayed on the file design screen 158 of FIG. 59 and “quantity” is to be deleted, first, edit (E) is selected to delete from the work options 200k displayed ( Select D) and then select the item of "quantity" to be deleted from the sales log file. This deletes the "quantity" and shifts the "unit price" and "amount" to the left by five digits as shown in the file design screen 159 (because the deleted "quantity" item has five digits). "@F
ILER ”is changed from 5 digits to 10 digits.

Next, an example of adding new definition information to the definition information of a file will be described. A "course number" is newly added to the course master of the file design screen 160 displayed in FIG. In the case of adding, the insert (I) is selected from the work options 200k displayed when the edit (E) is selected in the same manner as the procedure described above, and the position to add the definition information is further specified. Since the position for inserting the definition information is inserted before the “subject name” in the subject master, the item definition screen 161 is displayed when the cursor is moved to the 23rd column and clicked. Item definition screen 1
At 61, the item name, name, type, and length of the definition information to be added are specified. According to FIG. 60, the item name is “K_
NUM ", name" subject number ", type" 9 ", and length" 4 "are specified. Further, when a comment is to be added to the definition information, the program designer can arbitrarily input it. Finally, when the number of elements to be added is input and the setting button 161a is clicked, the "subject number" is added before the "subject name" like the subject master displayed on the file design screen 162 in FIG. 61. "Course name", "Balance at the beginning of the period", and "Actual results for the current period" are each shifted to the right by 4 digits (because the length of the added "Course number" is 4 digits).

As described above, the program designer can insert and delete by referring to the definition information of the file on the screen by using the input / output component designing section 7. It is possible to edit the definition information of the file more easily than to edit by handwriting. Also, if the file definition information is centrally managed by the system, all designers who use this file definition information can prevent designing without knowing that the file definition information has been changed. .

Example 6. In this embodiment, an example will be described below in which the program source generation means 9 of FIG. 1 automatically generates a program source based on the program information transmitted from the hierarchical structure design means 1.

FIG. 62 is a view showing a processing instruction sheet of the program source generated by the program source generating means 9 based on the processing contents displayed on the detailed design screen 132 of FIG.

In this embodiment, the hierarchical structure design means 1 is
The program source generation means 9 uses the processing content displayed on the detailed design screen 132 of FIG. 41 as program information.
And the program source generation means 9 automatically generates the program source. The automatically generated program source is as shown in FIG. Note that FIG.
The program source shown in
It is a program source in (Simple programming language by Mitsubishi Electric Corporation).

The first line in FIG. 62 corresponds to the first line in FIG. The first line in FIG. 62 is a program source corresponding to the specification for inputting the customer code from the screen and branching to the end processing when the input customer code is '999'. Since the detailed design process is part of the heading process according to the progress II specifications, the paragraph name is "H".
"D". Further, according to FIG. 41, the 23rd line of the screen is cleared after the customer code is input from the terminal, but since this program uses the standard error processing, it is not necessary to use the screen clear command in particular. , The 23rd line of the screen displaying the error message in the standard error processing is cleared. “TCODE” is an item name for a customer code that is defined in advance in the definition information that defines the screen input / output information. The branch destination "TE" indicates the paragraph name of the ending process according to the progress II specifications. In the second line of FIG. 62, the customer master file is read using the customer code as a key.
The read result is set to "99" because it is set to set "99" to the indicator when designing the processing contents of random file input (FIG. 47 (C)). ). The condition that the indicator is set to "99" is that there is no corresponding customer code in the customer master file. The sign is "99" on the third line of FIG.
If it is, the instruction branching to the standard error processing is specified. This corresponds to the processing content of the fifth line in FIG. According to FIG. 41, after branching to the standard error processing, branching to re-input is again made, but in FIG. 62, there is no instruction branching to re-input. This is because the standard error handling is used, and the standard error handling is designed to return to the beginning of a paragraph after displaying an error message. When the customer code corresponding to the customer master file exists, the customer name is displayed on the screen. In FIG. 62, this command is specified in the fourth line. “TNAME” is an item name corresponding to a customer name defined in advance in the file definition information of the customer master.

Next, although the total value is set to 0 in FIG. 41, this is specified in the fifth line of FIG. Since the total value is a numeral type and has thirteen digits, the transfer destination type is "9" and the length is "13" in the fifth line of FIG. Finally, the detail screen is cleared, but this is shown in FIG.
It is specified in line 6 of 2. “MEISC” is a screen output text name defined to clear the screen definition file for sales slip input.

Example 7. In the sixth embodiment, the standard error processing is used when the program source is automatically generated. However, when the program source is generated without using the standard error processing, it becomes as shown in FIG. FIG. 63 is a diagram showing a program source generated based on the detailed design content of FIG. 41 without using the standard error processing. In the first line of FIG. 63, the customer code is input from the screen and at the same time, the 23rd line of the screen displaying the error message is displayed as “CLTEX.
Clear by "T". In the second line, when the inputted customer code is '999', "80" is set in the flag. The fact that TCODE is '999' means that the process branches to the end processing. Therefore, if the flag is "80" in the third line, that is, if '999' is input to TCODE, the process ends. It branches to processing (TE). On the 6th line, if the input customer code does not exist in the customer master file, an error message is displayed on the 23rd line of the screen using "ERTEXT". Then, in the 7th line, the process is returned to the beginning (1st line) of the process in order to input the customer code again from the screen. Incidentally, “CLTEXT” and “ERTEXT” are defined in advance in the input / output design of the screen to clear the line displaying the error message and to display the error message.

As described above, in the sixth and seventh embodiments, the program source generation means inputs the program information from the hierarchical structure design means, and automatically generates the program source based on this program information. For this reason, the quality of the created program source was not constant according to the skill level of a programmer who coded a program as in the past, but if the program source creating means automatically creates the created program source, The source is a standardized program source with a certain level.

Example 8. In the above-mentioned seventh embodiment, the program source generated by the program source generating means 9 is generated based on the specification of “Progress II”.
However, since the program designing method in the present invention is a designing method that does not depend on the program description language, the program source generated by the program source generating means 9 may be, for example, "C language" or "COBOL". Absent. Although not shown in the drawing, when the program source generation means 9 receives the program information from the hierarchical structure design means 1 and automatically generates the program source, the program designer specifies the program description language on the screen. It is possible to easily automatically generate program sources in various kinds of program description languages.

Example 9. In the seventh and eighth embodiments, the program source generation means 9 only automatically generates the program source from the program information. However, the generated program source is further compiled to generate a program in an executable format. It is also possible. This allows the program designer to smoothly perform a series of system development work from program design to program test.

Example 10. In this embodiment, a specific example of the method of extracting program components by the input / output component extraction unit 11 in FIG. 1 will be described below.

FIG. 64 is a diagram showing a sample list of existing program sources. FIG. 65 is a diagram showing the program components input by the existing program source of FIG. 64 and extracted by the input / output component extraction unit 11. FIG. 66
FIG. 8 is a diagram showing an example of a program part extraction condition setting screen.

The program source of the sample list of FIG. 64 is stored in the existing program source 10a of FIG. The input / output component extraction unit 11 inputs the program source and automatically extracts the program component based on the extraction condition. The extraction condition in this embodiment is to extract a program step whose sixth column is the letter "J". The program source name and extraction conditions to be entered are set by the program designer in the extraction condition setting screen 16 shown in FIG.
By 3, the setting can be made arbitrarily. Further, it is possible to specify a program component name when the extracted program component is stored in the input / output component storage unit 8. In this embodiment, for example, the program name of the program source in FIG. 64 is "AAI8010", the extraction condition is "6th column = 'J'", and the program component name is "AAI801".
0D ”and set on the extraction condition setting screen 163. When the setting button 163d is clicked after the setting is completed, the parts are extracted, and the “AAI8010
The program parts as shown in FIG. 65 extracted by the file name "D" are stored.

Although only one program source is specified in this embodiment, a plurality of program name input areas shown in FIG. 66 are used to sequentially input a plurality of programs, and program parts are input under the same conditions. It is also possible to extract. If the program part name input area in FIG. 66 is also plural, a plurality of programs are sequentially input, program parts are extracted under the same condition, and the extracted parts are input / output parts with program part names corresponding to the program names. It is also possible to store in the storage unit 8. Furthermore, it is also possible to connect a plurality of conditions with “AND” or “OR” as extraction conditions. Therefore, the extraction conditions can be varied, and the program parts can be flexibly extracted.

As described above, by using the input / output component extraction unit 11, the program component can be set to the condition specified by the program designer even from the existing program source designed without using the program design method of the present invention. Since the data can be extracted based on the above, the program diversion can be improved. Further, also in the case of maintenance of the past system, since the program is highly applicable, it can be easily realized at low cost.

Example 11. In this embodiment, the program source generating means 9 and the input / output component extracting means 11 among the respective means and respective parts in FIG. 1 described in the first to tenth embodiments are hardware in which other means and parts function. In the following, an example of functioning on another independent hardware will be described below.

FIG. 67 is a block diagram showing that the program source generating means and the input / output component extracting means function on hardware independent of other means and parts in FIG. In the figure, the hardware A13 is composed of a hierarchical structure design means 1, an input / output design means 2, an input / output component storage unit 8, an input / output component design unit 7, a processing design unit 4, and a processing procedure storage unit 5. The hardware B14 includes a program source generation unit 9, a program source 10, an existing program source 10a, and an input / output component extraction unit 11.

Next, the flow of processing will be described with reference to FIG. In the hardware A13, the designed program information is L by the hierarchical structure design means 1.
It is transmitted to the program source generation means 9 of the hardware B 14 through the AN 12. The program source generation means 9 generates the program source 10 based on the transmitted program information.

As described above, since the hardware A13 in charge of designing the program information and the hardware B14 in charge of generating the program source are independent from each other, for example, the hardware A13 is composed of a portable personal computer. If so, you can bring this personal computer to the customer and design program information such as customization in front of the customer, and you can easily and quickly create a program that meets the customer's requirements. .

Example 12. In the eleventh embodiment, one set of hardware A13 is set to one set of hardware B14, but it is also possible to connect a plurality of sets of hardware B to one set of hardware B14. is there.

Example 13. Further, the above-mentioned Examples 11 and 1
In 2, the hardware A13 and the hardware B14 are L
Although it is assumed that the AN12 is used for connection, the same effects as those of the above-described first to twelfth embodiments can be obtained with other communication lines such as public communication lines.

[0150]

According to the first aspect of the present invention, by designing a program using a hierarchical structure, the contents of processing in each hierarchy become clear. For this reason, the program designer can easily design the processing contents, improve the productivity of the program design, and easily and swiftly create a program that satisfies the customer's requirements. . The input / output design is performed by the input / output design means using program parts. For this reason, the program designer has the effect that it is possible to perform the input / output design more easily and accurately by using the program component than to newly perform the input / output design.

According to the second aspect of the invention, the processing design means sets a processing procedure for each processing unit in each of the layers, and the processing content is designed according to the processing procedure. Therefore, the program designer can prevent the omission of the design of the processing and the order error by setting the processing procedure in advance. In addition, since the processing content is designed according to the processing procedure, there is an effect that it is possible to design while organizing the processing content after sufficiently understanding the context of the processing.

Further, according to the third invention, when the processing design means designs the processing content, the program component can be used. Therefore, for example, if a file for screen input is set as a program component, the program designer should set the processing content using the same item name as the data in the file when designing the processing content. Since the program components and the processing content match, the person other than the program designer can easily understand the design content.

According to the fourth aspect of the invention, the processing procedure storage unit categorizes the processing procedure into a specific pattern and stores it. Therefore, the program designer has the effect of easily selecting the corresponding pattern according to the program specifications to be designed, and easily setting the processing procedure. Moreover, there is an effect that the program to be designed can be standardized by patterning the processing procedure.

According to the fifth aspect of the invention, the input / output component design means supports the setting operation of the program component. Therefore, the program designer can refer to the file or the screen format on the same screen where the design is performed without checking the data of the file design document or the screen design document before setting the program parts. There is an effect that the input / output design can be performed more easily and surely than the first invention. Further, since it is possible to use another program component that already exists and create another program component, there is an effect that input / output processing can be performed quickly.

According to the sixth aspect, the program designer can refer to the program component by the input / output component designing means when setting the processing content. Therefore, the program designer has the effect of being able to use accurate item names and data types when setting the processing contents.

Further, according to the seventh aspect, when the program designer sets the program component, the input / output component designing unit is similar to the input / output component storage unit even if there is no appropriate program component. By taking out the program parts and customizing them, it is possible to easily obtain the necessary program parts, and there is an effect that the program can be efficiently designed. Further, the customized program component can be stored in the input / output component storage unit as a new program component. Therefore, when another program is designed, there is an effect that it can be immediately taken out from the input / output component storage unit and used without having to perform customization work again.

Further, according to the eighth invention, since the program generation means can automatically expand the program designed in the above first to seventh into the program source, the programming process by the program creator can be omitted, There is an effect that the program can be created quickly. In addition, since the automatically generated program source does not have a human error due to a mistake in understanding the specification, the quality of the finished product is kept at a certain level. Furthermore, since the standardized program source can be provided to the user, even if maintenance occurs in the future, there is an effect that the maintenance can be performed at low cost.

Further, according to the ninth invention, the input / output component extraction unit extracts the program component from the existing program source even if the program source is created without using the program design method according to the present invention. Therefore, there is an effect that existing assets can be effectively used, and system construction can be realized at low cost even when a system is newly constructed by using the program design method according to the present invention. Further, since the extracted program parts are stored in the input / output part storage part, the program parts can be easily customized using the input / output part design part, and the existing resources can be effectively used.
