Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a module reference method, and more particularly to a module reference method used when referring to detailed contents of a module described in a source file from a module configuration diagram.

[0002]

2. Description of the Related Art A conventional module reference method will be described with reference to FIGS. FIG. 8 shows source programs (801) and source files (802, 803) as terms often used in the module reference method.
And 804), module A-1 (805), module A-2 (806), module A-3 (807),
…………, Module B-1 (808), Module B
-2 (809), Module B-3 (810), ...
..., and module C-1 (811), module C
-2 (812), Module C-3 (813), ...
, Etc., and FIGS. 9A and 9B are views showing an image of a module list file in the conventional module reference method and a flowchart of the module reference method.

First, terms will be described with reference to FIG. Usually, the program in the information processing system is
This refers to a series of processing procedures for a computer to perform processing. In particular, the design rule invented to make it easier for humans to understand a program is called a programming language, and a program written in that programming language. This is called a source program (801). Further, the source files (802, 803 and 804) refer to files in which the source program (801) described in this programming language is actually stored, and usually one source program (80
1) is distributed and stored in a plurality of source files (802, 803 and 804). What is a module?
It refers to a functional unit that constitutes the source program (801), and normally, a plurality of modules exist in one source file.

Following the above explanation of terms, why the analysis work of the source program becomes important will be explained. In recent years, due to the increase in the scale of the system, the opportunities for multiple people to share the development of one system have increased, and under such circumstances, the source program that describes the system configuration also increases in scale, Opportunities to improve source programs created by others are increasing.
An important task is the analysis of existing source programs created by others. When a source program becomes large in scale, each module that constitutes the source program exists in many source files in a distributed manner. Therefore, it is important to search those modules quickly and analyze the structure of the source program. Analyzing the structure of the source program is equivalent to ascertaining the interdependence of each module that constitutes the source program and recognizing the detailed description content of each module. However, since each module exists in multiple source files in a distributed manner,
It tends to be time-consuming to search the description position of each module and refer to the detailed contents. The operation procedure of the conventional module reference method that enables easy retrieval of the module description position will be described below.

Conventionally, in the method of referring to the detailed contents of each module that constitutes a source program, a list (see FIG. 9A) showing which source file and where each module is described is based on a list. Then, the detailed contents of each module are referred to. In the conventional technique, as shown in the flowchart of FIG. 9B, which shows the processing procedure in the conventional method for referring to the detailed module contents, the source program is input to start the reference procedure, and the module list of the source program is started. Step 91 for creating the table file 901 and step 92 for designating the target module whose detailed contents are to be referred to
And step 93 of obtaining detailed content description position information of the target module from the module list file 901,
Step 94 for displaying the detailed contents of the target module from the description position information obtained in step 93, and it is judged whether or not to end this processing procedure. If it is ended, the processing is ended, and if it is not ended, , And step 95 for returning to step 92 again.

The conventional module reference method will be described in detail below. First, the structure of the source program input in step 91 will be described. FIG. 8 is a diagram showing the structure of a source file. The source program 801 includes a module group module A-1 (805) and module A existing in each of one or a plurality of source files (802, 803 and 804). -2 (806), Module A-3 (807) ...
…, Module B-1 (808), Module B-2
(809), module B-3 (810), ..., module C-1 (811), module C-2 (81
2), module C-3 (813) ...

In the conventional module reference method, a module list file 901 in which each module shown in FIG. 9A and related information indicating the position on the source file in which the module is described is described. As shown in the flowchart of FIG. 9B, each module is referenced while using the module list file 901. As the flow of the processing procedure, first, the module list file 9
01 is created in step 91, then the module name to be referred to is specified in step 92, and then the module list file 90 is specified in step 93.
From 1 specify the source file that describes the detailed contents of the module you want to refer to, acquire the specific description position information in the source file, and then
The detailed contents of the module corresponding to the acquired information are displayed in step 94. A specific example is shown in FIGS.

FIG. 10 and FIG. 11 are views showing an example of a conventional method of referring to the detailed contents of a module. As one practical example, as shown in FIG. 10, a computer screen (1001) is displayed. From the computer screen (1001) displaying the module A-1 (1003) described in the written source file, the module A-1-2 used in the module A-1 (1003) is displayed. As in (1006), the detailed module description (1004) of the module is displayed on the computer screen (1002) by designating the module name to be the target module, and as another example, , A computer screen 11 displaying the relationship between the modules and each source file, as shown in FIG.
From 01, by selecting a module to be a target module such as module A-1-2 (1103), the detailed content description part (1104) of the module
Is displayed on the computer screen 1102.

[0009]

In the conventional module reference method described above, at the time of program analysis,
Although it is possible to refer to the detailed contents for each module, there is a disadvantage that it is not possible to refer to the detailed contents of each module while grasping the overall configuration at the module level.

[0010]
