Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a Japanese-style reverse flowchart drawing device using a computer.

[Background of the invention]

FIG. 1 shows the hardware configuration of the flowchart drawing device. Central processing unit (hereinafter referred to as
CPU) 50, a card reader (hereinafter referred to as CR device) 51 and a magnetic storage device (hereinafter referred to as CR device) as peripheral devices.
52, a line printer device 53, an electrostatic printer device 54, and a console typewriter (hereinafter referred to as T/W) 55. CR device 5
1, a program source card written in a structured language (such as PL-1) is read, and its contents are temporarily saved in the DISC 52. The content of this saved source program is read, the execution procedure part thereof is analyzed, developed into an image, and drawn on the electrostatic printer 54. A conventional drawing method for such an apparatus will be explained.

FIG. 2 shows an example of conventional reverse flowchart drawing. Further, FIG. 3 shows an example of a source program for drawing the flowchart shown in FIG. Execution step numbers 10-18 in FIG. 2 correspond one-to-one with execution step numbers 10'-18' in FIG.
For example, step number 11 (1→SWA) in Figure 2
corresponds to step number 11' (SWA=1,) in FIG.

That is, conventionally, a source program shown in FIG. 3 was input, the contents of the program were analyzed, and a flowchart as shown in FIG. 2 was drawn. If you look at Figure 1, you can understand the execution procedure to some extent from the flowchart of the process. In addition, in the flowchart shown in Figure 2, the comments in the symbols are all alphanumeric characters, special symbols, and katakana characters, and are not output in kanji or hiragana characters, and the names are abbreviated.
How does the flowchart work?
The drawback was that it was difficult to understand from a third party's point of view. For this reason, when modifying a program that has already been completed and is actually running, if a third party other than the person who created the flowchart modifies the program, the meaning of the flowchart is difficult to understand. They had to understand the chart, which caused a decline in work efficiency.

Here, the relationship between FIG. 2 and FIG. 3 will be briefly described.

10, 10′...Indicates disclosure of MAIN PROGRAM.

11, 11'... Indicates that the number 1 is to be assigned to SWA.

12, 12′...Check if the SWA content is 1 by comparison.

13, 13'...When SWA=1, set zero to SWA.

14, 14′...Branch to RDMT module (when SWA=1).

15, 15′...Branch to PROCDT module (when SWA≠1).

16, 16'...Set zero to SWA.

17, 17′... Check whether the input data of RDMT is complete. If it is not finished yet, go back to 12, 12′.

18, 18'...If the data ends at 17, 17', perform program termination processing.

Although the explanation here uses a very simple program as an example, the actual business program is
Usually, it is incomparably more complex. In that case, if there are many comparisons, it will be difficult for a third party to understand the processing contents written in the flowchart by simply modifying alphanumeric characters, etc., and it will take a lot of time to decipher it.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a reverse flowchart drawing device for drawing a flowchart in which contents are displayed not only in special symbols such as alphanumeric characters but also in kanji and hiragana.

[Embodiments of the invention]

An embodiment of the present invention will be described below based on the drawings.

FIG. 5 is an example of drawing a flowchart according to the present invention, and 0 to 8 are processing sequence numbers of the flowchart. FIG. 6 is an example of a source program that serves as input data for drawing the flowchart shown in FIG. The numbers and text on the right side of Figure 5 are
There is a one-to-one correspondence with the processing sequence number shown at the upper left of the symbol in the flowchart on the left, and this is a supplementary explanation to convey to the flowchart reader what each symbol is intended to do. In this way, in the flowchart according to the present invention, supplementary explanations in Japanese are output on the flowchart. The original data for outputting this Japanese language is written in the comment section between /* and */ on the right side of the line in Figure 6.

In the present invention, the text data in /* to */ is examined and the following content check is performed.

When /- appears, it indicates that the flowchart drawing comment text is described below. Also, the end of a comment sentence is when -/ or */ is detected.

Commas (,) are used to separate words, words, sentences, sentences, etc. If one data part (word or sentence, etc.) separated by commas (,) is called an item below, one item may indicate a kanji or a sentence (for example, "add data" may be one It can also be an operator such as item) or two or ten.

When the beginning of the item is /C...slant and character C..., /C〇〇〇〇 indicates that 〇〇〇〇 is the index key for searching the kanji and terminology master stored in DISC52. . This 〇〇〇〇 is actually used in alphanumeric characters and katakana. For example, /C symbol indicates the term master of the Kanji term "initial value". That is,
When searching the term master file stored in DISC52, search the term master file using the four characters "shiyokichi" as the index key, and use the "initial value"
You can read out the kanji creation data.

If an item starts with a double quotation immediately after a comma, such as ..., “ABCD”, “data”, …, the data up to the next double quotation is treated as characters, and the above example becomes 〓 The contents of the seven-character entry item ABCD〓 will be output on the flowchart as drawing data.

Note that the numbers in FIGS. 5 and 6 indicate the same content, and in FIG. 6, a dash is added to the numbers.

Next, the flowchart drawing method will be explained.

Drawing of MAIN in Figure 5: Draw from the part written as "MAIN" in the line indicated by O' in Figure 6.

Figure 5/Drawing of SWA: Draw from the part "SWA:=1;" in line 1' of Figure 6. number 1
This means assigning to SWA.

Drawing the comment “ISWA:=1;Initial value=1,SET” part on the right side of Figure 5: This is the comment line of line 1′ in Figure 6./*/-U;/C, "=1 , SET*/”. (Here, U indicates one space.) (a) Create the output part of "/-U;" and "/USWA=/U;", and (b) Create a term master from the data "/C syokichi". Search for "shiyokichi" as an index key and create output data for the kanji term "initial value".

(c) Furthermore, analyze the data “=1, SET” */ and create the output data “=1, SET”, and from the data in (a), (b), and (c) above, create the following number. 5
Supplementary explanatory text as shown on the right side of the figure is output on the flowchart. That is, “/USWA:=
An explanation of the part surrounded by " will be output, such as "1; Initial value = 1, SET." Here, enter 0' and 1' as a representative example of the source program in Figure 6. The procedure up to outputting flowcharts 0 and 1 shown in FIG. 5 will be explained with reference to FIGS. 1 and 7.

If the source program, which is the input data for the reverse flowchart, is punched onto a card, the console typewriter 55 instructs to start a program for converting the data medium from the card to the disk (FIG. 1A). This will start the program. Then, when the source program is set in the card reader 51, the recorded contents of the card (1
~80 columns) is the SRG of disk 52 as it is
Output to file.

The data format of the SRG file is 6th.
As shown in the figure, the data record length is 80 characters, and the card data is in the same format as disk 5.
This is what was output in 2.

Next, the processing procedure of the apparatus of the present invention will be described using as an example two source programs of disk data sequences MAI00010 to MAI00020 shown in FIG.

First, a command to draw a reverse flowchart is entered from the console typewriter 55 (FIG. 1D).
This starts the drawing program and drives the disk 52.
source program file (i.e. S
OPRG file) to the first data, i.e. the 6th
In the example shown in the figure, data No. 1 whose card sequence (columns 73 to 80) is "MAI00010" is written into the main memory of the central processing controller 50.

Next, the plotting program examines the contents of columns 1 through 72. No. 1 data is only the symbol name “MAIN”. Since this data is the beginning of the module, it is the starting symbol of the module...〓
〓 Outputs... The data for drawing this start symbol itself is stored as one of the figure masters in the disk 52.

The drawing program reads the drawing data of the module start symbol from the master file on the disk 52 based on the key code of the module start symbol, combines it with the output position of the figure and the output character (in this case "MAIN"), and creates a flowchart. Output to drawing data (FLWDT) file (first
Figure). This completes the first data processing.

Next, the drawing program inputs the second data, that is, the No. 2 data in FIG. 73 of input data
The sequence N for columns ~80 is "MAI00020". Next, examine the descriptions in columns 1 to 72. The description contents are (i) Command part…“SWA:=1”, (ii) Comment part…“/＊/−;/C しょきち,”
=1, SET”−/*/.

Among these, SWA:=1; is an assignment, and ";" means the beginning and end of an instruction statement. In this case, set 1
This means that it will be saved in a data area named SWA, and since it does not specify the shape, it will read out a rectangular shape and insert “1 →
SWA" to create 1-SWA drawing data as shown in processing sequence No. 1 in Figure 5, and output this to the FLWDT file on the disk 52 in the same way as the module start drawing data described above. Note that the figure instructions are is set in the source program, such as instructing 〓〓 by IF and 〓〓 by CALL.

Next, the comment part is processed. In this case, when "/*" is followed by "/-" as in "/*/-", it means that the comment information for drawing the flowchart continues after "/-".

The general way to write the comment part is /-(A);(B)
−/ shall be configured. in this way"/
The part from “-” to “-/” means the comment to be output to the flowchart. Furthermore, “;”
(A) is a comment to be output in the figure of the flowchart. For example, in the figure of sequence 7 in Fig. 5, 〓Is the data complete? 〓This is a comment. Part (B) is a comment text that is output to the supplementary explanation column on the right side of the flowchart.

Since this comment part has the structure of /-;(B)-/, /C, "=1, SET" will be output to the supplementary explanation column on the right side of the flowchart.

As described above, the terminology master file on the disk 52 is searched using "shiyokichi" as the search key (see FIG. 1), and the kanji code of the kanji "initial value" is indexed and set as output data. Then a comma (,)
Next, set =1, SET surrounded by " in the output area in the same way to create output data for the comment field, and set the command statement "SWA:=1" and the output position of the comment statement to this. on disk 52
Output to FLWDT file.

In this way, the drawing data for one module is created and once the drawing data is stored on the disk 52.
Output to FLWDT file (Figure 1 H). After that, input the FLWDT file (Figure 1 H),
The figure is output to the electrostatic printer 54 (FIG. 1).

If a mistake is made in the source program or a code that is not in the figure master or term master is specified, an error message is sent to the line printer 53.
(Figure 1). In this way, in the present invention, as shown in the source program example in FIG. 6 and a part of the same source program in FIG. Items are filled in using Japanese characters, alphanumeric characters, katakana, and special characters according to the rules, and a combination of these characters makes it possible to create explanatory text in Japanese. This makes it possible to automatically draw content similar to conventional handwritten flowcharts. In addition, if it is found that there is an error in such drawing data, save the source program itself for drawing the reverse flowchart as data on the DISC52, correct this data, and then operate the device again. As a result, a revised flowchart can be obtained.

In addition, although the case where a drawing is output to the electrostatic printer 54 has been explained above, a CRT device capable of copying the screen is connected instead of outputting from the electrostatic printer.
First, the drawing data to be output to the electrostatic printer is displayed on the cathode ray tube of the CRT device, and the operator checks the screen displayed on the cathode ray tube, and if necessary, requests the contents of the screen to be output to the hard copy device. Also good.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to perform work such as modifying or changing a flowchart, which was conventionally done by hand, on a machine basis, and it is possible to perform work such as correcting or changing a flowchart, which was conventionally done by hand, and to make it possible to do it formally in the process of flowchart → coding, as in the past. Instead of creating a formalized flowchart and then coding it, you can create a flowchart by hand and immediately enter the coding, which saves you the labor of formalizing it. Furthermore, if you have the source program after debugging, you can immediately draw a flowchart, so if you have the latest source program, there is no need to modify the flowchart that has already been created, which saves labor.

From the above points, work can be streamlined, productivity can be improved, and uniform, high-quality flowcharts can be obtained.
