Abstract

PURPOSE:To improve the reliability of the titled analysis system by analyzing statically a produced program group and a JCL (job control language) and extracting the application form information to deliver it to a page printer. CONSTITUTION:A JCL information analysis part 3 reads the JCL source out of a file 1 and extracts the program name, the file code and the file name defined by the JCL to store them to an asign information file 5. The file 5 is formed as an index file mainly for program names and file codes. An item process analysis part 4 first analyzes a COBOL source program PRSO and develops the file name and the file data item name defined by a COBOL data defining part on a memory table provided in the part 4. Then a COBOL source code part is analyzed and the correlation information between the file name and the file data item name is stored on the memory table and outputted to an item process correlation file 6 when the analysis is over.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an element item processing correlation analysis system used in an information processing device.

[Technical background of the invention and its problems]

Conventionally, information processing devices have had "program procedure amount information analysis tools", "data dictionaries/directories", etc. It does not have functions such as outputting the program usage pattern. That is, the "program procedure amount information analysis tool" is a system that analyzes calling relationships regarding parameters used when a main program calls subprograms, but does not analyze file data item (element item) information.

Also, data dictionary/directory (DataD
ictionary/Directory)J,
Name of the data.

Attributes of the data, programs that use the data.

Chikuzu: It is registered and can be searched externally, but the data item (
Information indicating how the program uses the file (element item) or file (usage pattern) is not registered.

For this reason, in the past, problems remained in terms of efficiency in system verification, program verification, and the like.

[Purpose of the invention]

The present invention has been developed in consideration of the above-mentioned circumstances, and allows an information processing device to output the correlation between a program and a file, the correlation between a program and file data items, etc. in a state that can be easily recognized. It is an object of the present invention to provide an element item processing correlation analysis system that can efficiently perform system verification, program verification, etc. based on this output information.

[Summary of the invention]

The present invention is based on the manufactured program group and JCL (Job
Control Language) is statically analyzed,
By extracting and storing usage information for program files and file data items, and outputting the information to a page printer at any time, system verification is supported and system reliability is improved, and the stored information is referred to during system maintenance. By doing so, it is possible to easily understand the degree of impact of system changes.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a configuration diagram of a system in an embodiment of the present invention. In the figure, 1 is JCL (J

Assignment information file to be accumulated, 6 is source program PR8
This is an item processing correlation file that analyzes and stores O. 7 is a correlation table printing section that edits and prints files 5 and 6, a correlation table between programs and files outputted by the 8-digit printing section 7, and 9 is a correlation table between programs and file data items outputted by the printing section 7. be.

FIG. 2 shows a logical configuration diagram of the assignment information file 5,
FIG. 3 shows a logical configuration diagram of the item processing correlation file 6.

FIG. 4 is a diagram showing a correlation table between programs and files printed out by the printing unit 7, and FIG. 5 is a diagram showing a correlation table between the programs and file data item names.

Here, the operation of one embodiment will be explained. JCL information Information analysis Read the JCL source from the top 3 file 1, extract the program name, file code, and file name defined in JCL, and create the assignment information file 5 in the format shown in Figure 2.
Accumulates into f. The assignment information file 5 is structured as an indexed file, and the main index is the program name and file code. In the item processing analysis section 4, Maf C0B
Analyzing the OL source program PR8O, C0DOL
7'' - The file name defined in the file definition section and the file data item name are developed on the memory table in the item processing analysis section 4. Then, the C0BOL source code section is analyzed using the method described below, and the file name and the correlation information for the file data item name are also stored in the memory table, and after the analysis is completed, they are output to the item processing correlation file 6 in the format shown in FIG. 3.The item processing correlation file 6 is also configured as an index organization file. , the main index is the program name and file code.Table 11 Table 2 shows the source code analysis method.

Table 1 is the program source PR written in C0BOL.
Table 2 shows an example of information for analyzing the usage pattern (correlation information) for a file of a program written in C0BOL.

In other words, as shown in Table 1, C0B is included in the source code section.
OL file operation command word (for example, "READ"
, “DELETE”, “0PEN I-0”
) and the file name, it becomes clear how the file name is used by the program.

■In the case of ('''READ''), the file name is the data input target by the program, so it is
The code (input) of is defined as the form. Note that the usage format is I: input, -O: output.

M: modification, z: initialization, D: deletion, etc. Similarly, as shown in Table 2, ■ and ■, the C0BOL data operation command (for example, 'MOVE').

00MPUTE") and the file data item name, the usage pattern for the file data item of the sibling program can be determined. In "MOVE ' of ■, data item name 1 is data manual engineering, and data item name 2 is data modification. “
M'', each code is stored in the table memory.As a result, the correlation information between the program and the file can be obtained by the examples of ■ to ■, and the correlation information of the program and the file data item can be obtained by the examples of Correlation information can be obtained.

The correlation table printing unit 7 performs matching between the assignment information file 5 and the item processing correlation file 6 using the main index (by program name and file code), and rearranges them to produce the results shown in FIGS. 4 and 5. A correlation table can be obtained.

By using the above-mentioned correlation information, (1) it is possible to visually grasp the correlation between programs and files and use it as data during system verification; This can improve system verification efficiency.

(2) Correlations between programs and file data items can be visually captured and used as data during program verification. This can improve the efficiency of zologram verification.

(3) Using the correlation table, the degree of influence on files by program changes and the degree of influence on programs by file structure changes can be easily determined.

(4) Correlation information is stored in the assignment information file and item correlation file and can be referenced at any time.

(5) As correlation information, ′° large input, “correction”.

Since it is regarded as "output", 'deletion', and 'initialization', verification ability and maintenance ability increase.

(6) Since the correlation table is a two-dimensional array, visual judgment is easy.

etc., various effects can be achieved.

The above is an example adapted to the C0BOL language, but similar processing is possible for other computer languages. [Effects of the Invention] As detailed above, the element item processing correlation analysis system of the present invention According to , it supports system verification by statically analyzing manufactured program groups and JCL, extracting and accumulating usage information for program files and file data items, and outputting the information to a page printer at any time. In addition to being useful for improving system reliability, by referring to the accumulated information during system maintenance, it is possible to easily understand the impact of system changes.
