Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for creating a program specification from a source program.

[Conventional technology]

In system development work, system analysis work, general design, basic design, detailed design such as program specification creation,
Each task occurs in the order of program production, program unit testing, and system testing, but after such system development work is completed, the existence of program specifications is always important when system maintenance work occurs. come. This is because if there is a program for which a program specification does not exist, the relationship between the program and the programs before and after it is not clear, which causes problems in system maintenance.

Traditionally, program specifications have been created by hand using templates, rulers, etc.9.

In this case, it is usually created based on the basic design document, but the document is not complete or
When more detailed program specifications are required, S
Computer staff such as E were creating the program while referring to the program source list, flowcharts, etc.

[Problem to be solved by the invention]

In the conventional method of creating program specifications described above, computer personnel created the program specifications by hand, which required time for the documentation process. The disadvantage is that the expressions are different, and it is easy to make mistakes when creating or changing them, resulting in a lot of work time loss.

[Means to solve the problem]

The program specification creation method of the present invention includes a program reading means for reading a prespecified source program from a group of source programs, and a predetermined source necessary for creating a program specification for the source program. an information reading means for reading program information from the read source program; and based on the read source program information, editing the data necessary for creating the program specification, This configuration includes editing means for defining figures and ruled lines.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 shows the configuration of an embodiment of the present invention, Fig. 2 shows an example of the contents of a source program image file written in Kobol language input in this embodiment, and Fig. 3 shows the program specification obtained by this embodiment. An example is shown.

In FIG. 1, 1 is a source program sending section, 2 is a program reading section, 3 is a file section, 4 is a control section, 5 is a program header section reading section, 6 is an input/output section reading section, and 7 is a file section reading section. , 8 is a communication section reading section, 9 is a file opening reading section, 10 is a subroutine reading section, 12 is an editing section, 1
3 is a drawing control section, 11 is a data holding section, and 14 is a printer.

The source program sending unit 1 sends out a source program group stored on a magnetic tape or the like, and the program reading unit 2 specifies in advance that the program specifications should be created from among the source programs transmitted from the source program sending unit 1. The file section 3 selectively reads the source program that is being read, and the file section 3 converts the source program output from the program reading section 2 into a file.

The control unit 4 is a control unit that performs the following various controls in order to create a program specification.

The program header section reading section 5 reads a PROGRAM-- such as the one illustrated in FIG. 2, which is transmitted at the beginning of the program.
The program name shown in the ID statement 21, the name of the author of the writing desk 2 in the AUTHOR statement 22, and the DATE-WRITTEN
The creation date shown in the sentence 23 and the annotation lines 24 and 25 are analyzed to decipher the business name and processing outline.

The input/output clause reading section 6 reads the program environment section that is transmitted after the PROGRAM-ID statement 21, AUTHOR statement 22, D-written statement 2-WRITTEN statement 23, annotation line 24, 25, etc. that constitute the program header section. 5 in the input/output clause
It interprets the ELECT statement 26, including the internal file name of the file used by the program, the file structure, the access method, etc., and the definition information of the external medium used by the program, as well as the data transfer and processing between the execution program and the medium. It is used to decipher information related to

The file clause reading unit 7 reads the record length and block length of the file in the real file clause 27 that is transmitted after the 5ELECT statement 26 in the input/output section of the program environment section, and checks the existence of a copy command 28. be.

The communication clause reading unit 8 detects the existence of communication area information for exchanging information between the program and the communication management system by checking the communication clause 29.
It is to be inspected by

The file opening reading section 9 is a manual reading section of the program that analyzes the 0PEN command 30 when opening a file for input, output, input/output, or addition.

The subroutine reading unit 10 reads the name of a subroutine used by a program based on a CALL instruction 31 that transfers control from one program to another in a certain execution unit in the program procedure division.

The data holding section 11 includes the program header reading section 5. Input/output section reading section, file section reading section 7, communication section reading section 8. File opening reading unit 9 and subroutine reading unit 1
Data output from 0, for example, program name, internal file name, record length, etc., are held.

The editing section 12 edits and processes the data necessary for creating the program specifications, and also defines the figures and ruled lines of the program specifications, and the drawing control section 13 draws the diagrams necessary for creating the program specifications. The printer 14 outputs the program specifications and prints not only characters and symbols but also figures necessary for drawing the program specifications, such as figures and ruled lines to show the flow. You can also take it out.

The operation of this embodiment will be described below with reference to FIG. 2.

When creating a program specification, source program image files written in the Kobol language, the contents of which are shown in FIG. Only the source program that is currently available is read and sent to the file section 3. Then, the program is transferred from the file section 3 to the program header section reading section 51. Input/output clause reading unit 6゜File clause reading unit 71 Communication clause reading unit 8. File Opening Judgment Department 9. The information is sequentially transmitted to the subroutine reading section 10.

That is, PROGRAM-ID statement 21 and AUTHOR
The task name 24 and processing summary 25, which are composed of a statement 22, a DATE-WRITTEN statement 23, and an annotation line, are detected and analyzed by the program header section reading section 5, and are themselves read into the 5EL.
The ECT statement 26 is detected by the input/output cylinder reading unit 6 and contains the internal file name, file organization, access mode, etc. of the file used by the program, and the file clause 27 is detected by the file clause reading unit 7 and contains information about the file. The record length, block length, blocking factor, etc.
The 0PY instruction 28 is also the file section + (detected by the 1 reader 7 and the member name of the collection original text collection is also the communication section 29
The 0PEN command 30 is detected by the communication section judgment section 8 and the presence/absence information of the communication section is detected, and the 0PEN command 30 is detected by the file opening interpretation section 9 and the open mode information at the time of file opening is detected.
The ALL instruction 31 is detected by the subroutine reading section 10, and the subroutine names used by the program are each held in the data holding section 11.

After the processing by each of the reading sections described above, the control section 4 sends the editing section 12
Then, a control command is sent to the drawing control section 13 to read necessary data from the data holding section 11 and to create a program specification as shown in FIG. As a result, a program specification document clearly indicating the program name, necessary file names, flowcharts, etc. can be obtained from the printer 14.

In this embodiment, the output result is obtained in the format shown in FIG. 3, but if a simple parameter is given when instructing the creation of a program specification, the control section 4 and editing section 12 will be able to adjust the conditions of the specified parameter. You can also use dotted lines and solid lines or change the shapes in the chart section.

〔Effect of the invention〕

As explained above, according to the present invention, by executing a program specification creation program, a program specification can be created in a fixed format in a short time, and the program specification can be created in a short time compared to the conventional handwritten program specification. Unlike this, program specifications with uniform quality and no errors can be obtained.

Furthermore, no matter how many times a program is changed, it is output in a completely rewritten form, which greatly reduces the number of man-hours required for document work.
