JPH02161521A - Automatic formation method for source program from flow chart - Google Patents

Abstract

PURPOSE:To prevent a flow chart macro from being retrieved at the time of judging the macro as being unregister and to speed up processing by including information indication whether a flow chart macro is registered in a flow chart macro file or not is a flow chart marco reference part. CONSTITUTION:A flow chart macro detecting means 1 detects the flow chart macro reference part from a flow chart stored in a flow chart file 3 for storing the flow chart. A source program forming means 2 forms a source program by using information in a macro file 4 registering a flow chart macro film based upon the detected flow chart macro reference part. The formed source program is stored in a source program file 5. Macro information 6 constituting the flow chart reference part stored in the file 3 expresses the flow chart macro information, whether a flow chart macro shown by a flow chart macro name 7 is registered in the flow chart macro file or not is set up at the time of forming the flow chart, and when the information 6 is registered, the name 7 indicates the flow chart macro. When the information 6 is not registered, the name 7 is reflected to the source program as a comment.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for automatically generating a source program from a flowchart, and in particular, the present invention relates to a method for automatically generating a source program from a flowchart. Concerning automatic source program generation method.

(Prior Art) Conventionally, in this type of automatic generation method of a source program from a flowchart, a flowchart macro file is referred to each time a flowchart macro is called.

(Problems to be Solved by the Invention) The conventional automatic source program generation method described above has the drawback that it is difficult to improve processing efficiency because the flowchart macro file is referenced each time a flowchart macro is called.

(Means for Solving the Problems) The method for automatically generating a source program from a flowchart according to the present invention includes a means for pre-registering flowchart macros indicating common parts within a flowchart, and a means for pre-registering flowchart macros from within a flowchart. a flowchart macro detection means for detecting a flowchart macro reference part including macro information indicating whether or not the flowchart macro is registered in the flowchart macro file by referring to the flowchart macro reference part detected by the flowchart macro detection means; If there is no flowchart macro file, a source program generating means is provided for generating the source program without referring to the flowchart macro file.

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

FIG. 1 is a block diagram showing an embodiment of a method for automatically generating a source program from a flowchart according to the present invention.

In FIG. 1, a flowchart macro detection means 1 detects a flowchart macro reference portion from a flowchart in a flowchart file 3 that stores flowcharts. Based on the detected flowchart macro reference part, the source program generation means 2 generates a source program using the information of the flowchart macro file 4 in which the flowchart macro file is registered, and the source program thus generated is stored in the source program file 5. In the diagram, → indicates the flow of control, and the inside indicates the flow of information.

FIG. 2 shows details of the flowchart macro reference section in the flowchart file 3. Macro information 6 constituting the flowchart reference section represents flowchart macro information, and sets whether or not the flowchart macro indicated by flowchart macro 7 is registered in the flowchart macro file when the flowchart is created. When the macro information 6 indicates a registered state, the flowchart macro name 7 represents the flowchart macro, and when the macro information 6 indicates an unregistered state, the flowchart macro name is reflected on the source program as a comment. Ru.

FIG. 3 shows a flowchart showing the processing procedure of the flowchart macro reference portion detection means. The process consists of inputting the flowchart from flowchart file 3 (step 8), and determining whether it is the end of the file (step 9).
, if it is the end, the process ends. On the other hand, if it is not the end of the file, check the flowchart macro reference part while scanning the flowchart (Step 10); if it is a flowchart macro reference part, the flowchart macro reference part information 6 shown in FIG.
Step 11) Set the flowchart macro information based on
, go to the processing of the source program generation means 2. If it is not a flowchart macro reference part, the process goes to the source program generation means 2 (step 12).

The processing procedure of the source program generation means 2 will be explained with reference to FIG. Determining flowchart macro reference (step 13)
) is false (not a flowchart macro reference), a source program is generated (step 17), and step 14
In step 15), if the macro information 6 in the flowchart reference section indicates that a flowchart macro is registered, the flowchart macro file 4 is searched to find the flowchart macro indicated by the flowchart macro name 7. Information is obtained from the macro (step 16), and a source program is generated by replacing the flowchart macro reference part with the main body of the flowchart macro indicated by flowchart macro name 7.

゛? in the flowchart macro reference section? If the flowchart macro in the macro information is unregistered, the flowchart macro reference part is replaced with an annotation containing the flowchart macro name to generate a source program.

(Effects of the Invention) As explained above, the present invention provides the flowchart macro reference section with information as to whether or not the flowchart macro is registered in the flowchart macro file. Since the search is not performed, the processing speed can be increased.
