Abstract

PURPOSE:To obtain correct information by providing an information collection requesting means, an information informing means and an information editing means having respective prescribed functions. CONSTITUTION:An information collection requesting means 8 requests a data control routine 1 that file information executing an input/output processing is collected as the related information between the modules of a program when a processing program is operated. An information informing means 7 combined to the data control routine 1, when the request is executed by the request means 8, informs an information editing means 5 of the file information input/output- processed by a processing program. An editing means 5 collects the file information from the informing means 7 and edits so that the information concerning the file input/output-processed by the program can be registered as the intermodule related information of the program to a data dictionary directory system. Thus, correct information can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to program module related information of a computer data dictionary directory system (hereinafter referred to as DD/D8), and particularly relates to the collection of registration information thereof.

(Prior Art) The DD/D8 is effective when the information registered therein is accurate and has no omissions.

In the past, registration was done by humans looking at specifications and programs, and registration information was collected using a program that analyzed the source program.

(Problems to be solved by the invention) If the specification is not accurate, if one person makes a mistake, or if the program that analyzes the M-start program runs and the method for compiling and linking. If the environment is different from time to time, there is a problem that correct information cannot be collected.

The object of the invention is to describe information related to modules of a program without depending on the language.

By having the data management routine automatically and centrally collect data while the compiler or linker is actually operating, the above drawbacks can be removed and accurate information can be obtained. The object of the present invention is to provide a data dictionary directory system registration information collection method configured in the following manner.

(Means for solving problems) The DD/Da registration information collection method according to the present invention is as follows.

It is composed of an information collection request means, an information notification means, and an information editing means.

The information collection request means is built into a processing program such as a compiler or linker, and performs input/output processing when the processing program runs. This is a conflict to request the data management routine to collect file information that has been executed as information related to the modules of the program.

The information notification means is incorporated in the data management routine, and is used to notify the information editing means of the input/output processed file information by the processing program when a request is made by the information collection request means.

The information editing means increases the file information as notified by the information notification means, and edits the information about the file input/output processed by the program so that it can be registered in the data dictionary directory system as inter-module related information of the program. It is for the purpose of

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

FIG. 1 is a block diagram showing an embodiment of a DD/D8 registration information collection method according to the present invention.

In FIG. 1, this embodiment includes a data management routine (DM)l, a compiler and linker (CPL) 2, an input library (LBI) 3, and an output library (LBO).
4, an information editing means (DDE) 5, and a %DD/D8 information storage virtual file (DDD) 6. The information notification means 7 is incorporated in the DMR1.

The information collection request means 8 is incorporated into the CPL 2.

The data management routine DMR1 is a part of the operating system that performs file input/output processing, and all file input/output by the compiler and linker is performed through this data management routine. input library LB
I3 is.

The source program input to the compiler, C0BOI,
Language registry, PL/I language include files,
Alternatively, it is a library that stores multiple compiler object programs that are input to the macro and linker.

The output library LBO4 is a library in which a plurality of object programs output by the combiner 2, object programs output by the linker, and load modules output by the linker are stored.

The information editing means DDE5 is incorporated into the data management routine and collects related information between modules of the program and
/D8 Performs output processing to the information storage virtual file. DD/
The Da information storage virtual file DDD6 is a virtual file that stores the DD/D8 related information collected by the DDD5, and may be the DD/D8 file itself, the main memory, or the disk file. Tashi.

The compiler and linker CPL2 uses the DD before processing.
The data management routine DM is notified by the information collection request means 8 that the /D8 information will be collected and that processing by the 57 Pie 2 or linker will begin.

If the data management routine DMR1 receives the notification, it will either terminate the processing of CPL2 or
Each time the file input/output processing is completed until the next notification is received from Lz, the information notification means 7 notifies the 9DD] 135 of information regarding the file and collects the %DD/DS information.

This is because generally all file input/output is started by open processing, which is a pre-processing that performs actual input/output, and the above open processing is performed regardless of the file type.
Focusing on the fact that this is done using the same routine, we added the above D D to the open routine of this data management routine.
/DS It is possible to perform processing to collect S information.

Does DDE5 collect DD/DS information from CPL2?
After receiving the notification through the request vDMR1t-, will the processing of CPL2 be completed?

Or CPL2 waits until the next notification is received from CPL2.
DD/DS information is collected as one processing unit. The DDE 5 assumes that the LBIa module input first refers to the LBIa module 7 input thereafter. Also, within one processing unit of ePL2, it is assumed to have been created by a module that was output to LBO4 and input later after receiving notification from module 9. DDE5[.

Related information between the modules of the above program Sound D D/
The information editing means DDEsvf is used as the DS information and output to the DDD6.

The actual processing flow fLt will be explained using the busy%C0BOL compiler as an example.

The second prisoner shows the contents of the source program P 09 that is to be translated by the COBOL compiler, and it is assumed that the source program includes the CO)'Y instruction.

FIG. 3 is an explanatory diagram showing the contents of LBIa in which a plurality of source programs and C0BOL language registration collections are stored. In FIG. 3, IM start program)'1(,C9
And the registration collection CI'Y which is fraudulently identified by P几G9
lO is stored.

C0BOL combination, program P 09 on 7CPL2
When a translation request is made, the %C0BOL compiler CPL
2 writes LBI3 to the data management routine DMR1.
File above) 'Sends an open request, which is input preprocessing for RG9.

At this time, depending on whether or not collection of DD/Da information is specified using translation options or SG parameters, D
The collection of D/Da information is notified to the data management routine DMRx as a parameter when opening the file.

The open routine of the data management routine DMR1 notifies the information editing means DDB5 to collect all %DD/Da information since the C0BOLr translator has started translating the program program PRG9 on the library LBI3.

DDB5 is the original program name and library salt.

Also, information representing the translation by the COBOL compiler is saved in the main memory.

FIG. 4 shows the state of the information save area TBL11 held in the main memory of the DDE5 immediately after the start of translation processing.
Contains information about source programs.

C0BOL compiler CPL2 is the source program PR,
When you encounter the C0PY instruction in the process of translating G9,
The 0BOL compiler CPL2 sends an open processing request for the file CPY10 in the library LBIa corresponding to the library name specified by the COPY command to the open routine of the data management routine DMR1.

The open routine is for file open requests from the COBOL compiler CPL2.

All information will be notified to the information editor RDDE5. Therefore, in this case as well, the information editing means DDE5 is notified that there is an input request for the file CPYIO on the library LBIa. The information editing means DDE5 is a source program PR.
File CPY1 on library LBI3 for G9 translation
0 is used and the information 9 is saved to the main memory.

Similarly, the C0BOL compiler's primitive Googram PRG
In the translation process of 9, each time the C0PY instruction appears, the information of the file on the library corresponding to the registered prefecture name is saved to the main memory.

C0B (When the JL compiler CPLz finishes translation and outputs it to the object program 0BJ7 library, the C0BOL compiler CPL2 issues an open request to the data management routine DRM l as preprocessing of the output. This request.

After all, the information editing means DDE5 is notified, and the information editing means DDE5 receives the information that the object program OBJ has been created on the library LBO4. Save to TBL11.

FIG. 5 shows the contents of TBLll immediately after the C0BOL compiler CPL2 outputs the object program, which is the source program.

Information regarding registration collections and object programs is stored. When the processing of the C0BOL compiler CPL2 is completed, the operating system calls the data management routine DMR1, which is a post-processing companion for the file, and the data management routine sends the C0BOL compiler to the information editing means DDE5.
Notify that the BOL translation process is complete. Information pD stored in information editing means DDEsHTBLx 1
It is edited as D/Da information and output to disk file DDD6, which is a virtual file storing DD/DS registration information.

FIG. 6 is an explanatory diagram showing the contents of DDD5.

The DDD 6 stores and layers information regarding the source program, the registry, and the object program. Information that the source program is a C0BOL source program, is stored as PRG in the library LBI, the registry used is created in CPY on LBI, and the object program is OBJ on LBO. is stored. The registration collection is stored as CPY on the library LBI.

The registration collection stores information that it is referenced by the source program PRG. The object program is stored as OBJ in the library LBO by the C0BOL compiler (A# in the D object program), and the information that the source program used to create this object program is PRG in the library LBI is stored. Stored. Although this information differs depending on the operation mode, it is collectively stored in the pDD/DS database according to a separate DD/D8 registration course.

(Effects of the Invention) As explained above, the present invention automatically stores information related to the modules of a program in the data management routine when the compiler or linker is actually operating, without depending on the writing language. This can be done by collecting the waste in a targeted and centralized manner.

The related information between the modules of the program registered in D D/D 8 is actually the same as when the compiler and linker operate, so you can obtain accurate and complete information. There is an effect that says it can be done. Furthermore, since the module related information is collected by the data management routine, there is an effect that the related information between the modules of a program can be obtained using an existing compiler or linker without depending on the language.
