Referring to FIG. 8, the processing in the source program analysis apparatus of this embodiment includes a module selection step 101, a step 102 of retrieving the own module name and the used module name, and a step 103 of storing module structure information in the analysis result storage means. , a step 104 for determining the presence or absence of reference module structure information for the same module name, a step 105 for determining the success or failure of all used module names, and a step for obtaining the module function description from the reference comment storage means and storing it in the comment storage means]06 , a step 107 for obtaining module function descriptions from the user and storing them in the comment storage means, a step 10B for determining whether all module processing has been completed, and a step 109 for outputting module structure information with module function descriptions added. Next, the operation of the source program analysis apparatus of this embodiment configured as described above will be explained.

When reanalyzing a source program, first the source program describing the current software system is stored in the source program storage means 1 along with its own module name for each module A, B, . . . , and the reference analysis result storage means 3 Reference module structure information for each module that constituted the software system at the time of the previous analysis is stored in the reference comment storage means 7, and reference module structure information for each module that constituted the software system at the time of the previous analysis is stored in the reference comment storage means 7. The own module name and 1,000 joule function description are stored.

From the above state, the source program analysis means 2 selects one module from modules A, B, . . . stored in the source program storage means 1 using the source program reference section (step 101). ，
The self-module name of the selected module is retrieved and stored in the self-module name storage area, and the source program of the selected module is analyzed and the word that appears following the call (CALL) in the source program is recognized. The names are extracted and sequentially stored in a plurality of used module name storage units (step 102). When the source program reference section of the source program analysis means 2 stores the own module name and the used module name in the own module name storage section and the plurality of used module name storage sections, the analysis result update means 4 Enter the own module name and used module name from the own module name storage area and the used module name storage area in stage 2, and store the module structure information consisting of the input own module name and used module name in the analysis result storage stage 5. (Step 103). Next, the analysis result updating means 4 searches the reference analysis result storage means 3 based on the own module name input from the source program analysis means 2, and searches the reference analysis result storage means 3 based on the own module name input from the source program analysis means 2, It is determined whether there is reference module structure information having the module name (step 104).

If it is determined that there is reference module structure information with a matching own module name in the reference analysis result storage means 3,
The analysis result updating means 4 compares all the used module names input from the source program analysis means 2 with all the used module names of the reference module structure information, and determines whether the used module names in all match. In step 105), if it is determined that all the used module names match, the judgment result indicating that the module function description is to be obtained from the reference comment storage means 7 is sent to the source program analysis means 2 which manually inputs the own module name. The comment update means 8 is notified along with the name. If it is determined in step 104 that there is no reference module structure information in the reference analysis result storage unit 3 whose own module name matches the own module name manually input from the source program analysis means 2, and in step 105 it does not match the used module name. If it is determined that there is a problem, the module analyzed by the source program analysis means 2 is a module that was added after the time of the previous analysis, or the content of the source program is added to the content of the source program after the time of the previous analysis. Since this is a module that has been added, changed, or deleted, analysis result update 1000 steps 4 comments with the judgment result indicating that the module function description is to be obtained from the user along with the own module name manually created by source program analysis 1000 steps 2. Notify update means 8. When notified from the analysis result update 1000 steps 4 of the own module name and the judgment result indicating that the module function description is to be acquired from the reference comment storage means 7, the comment update means 8
searches the reference comment storage means 7 based on the notified own module name, retrieves the module function description corresponding to the own module name, and stores it in the comment storage means 9 together with the own module name notified from the analysis result update means 4. do(
Step 106). When the analysis result updating means 4 notifies the user of the own module name and the determination result indicating that the module function description is to be obtained from the user, the comment updating means 8 receives the user's request for the comment input means 6. prompts the user to input the module function description, obtains the module function description input by the user from the comment input means 6, and uses the module function description obtained from the user together with the own module name notified from the analysis result update means 4. The comment is stored in the comment storage means 9 (step 107). When the above processing for one module is completed, the source program analysis means 2 determines whether the source program analysis processing for all modules A, B, . . . in the source program storage means 1 has been completed. is determined (step 108), and if there is an unprocessed module, control is returned to step 101.

The processing from the steno knob 101 to step IO8 is repeated until it is determined in step 108 that the analysis processing for all modules A, B, . If it is determined that the analysis processing for B, . The module function descriptions are read out, and module structure information to which the module function descriptions are added is output for the modules that constitute the current software system (step 109). In this way, the source program analysis bag of this embodiment is
Given a source program, reference module structure information created when the source program was previously analyzed, and module function descriptions for all modules for which reference module structure information has been created,
Add to modules added and used by the user since the point when the source program was previously analyzed.
New module structure information and module function descriptions can be created simply by inputting the module function description of the module that has been changed or deleted. In addition, in the above embodiment, the case where the analysis result is module structure information and the comment information is module function description is explained, but the present invention can be similarly applied even if the analysis result and comment information are different information. It goes without saying that it can be done. [Effects of the Invention] As explained above, when re-analyzing a source program, the present invention allows the machine to analyze the source program, the previous analysis results of the source program, and the source program input manually at the time of the previous analysis. By comparing the previous analysis results with the current analysis results when comment information that cannot be retrieved is given, the user can simply enter the comment information that needs to be updated and receive the new analysis results. This eliminates the need for the user to re-enter comment information that does not need to be updated, thereby improving the efficiency of source program analysis.
