Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, the name of a data item used by a program, the name of a record to which the data item belongs, the name of a file to which the record belongs, the name of a program using the data item, etc. are written. The present invention relates to an apparatus and method for creating a stored program dictionary.

Traditionally, cross-references that span multiple programs have never been taken care of by the compiler. So, for example, if you want to increase the length of a data item called "department code" by one digit, to find out what the program accessing this data item is, look at the source list, Or it was necessary to check the program specifications.

For this purpose, the name of the data item used by the program, the name of the record to which the data item belongs, the name of the file to which the record belongs, and the name of the program using the above data item may be registered in the program dictionary. Has been done. However, conventionally, the process of compiling a source program and the process of registering information in the program dictionary have been completely separate. Therefore, the source program was compiled to create a load module, but the information was not registered in the program dictionary, or the opposite occurred, and the program dictionary correctly reflected the information of the current load module. It causes the situation that they have not done it (at different levels). This allows the program
It has the drawback of losing the authenticity of the dictionary.

The present invention is based on the above consideration, and an object thereof is to create a program dictionary that correctly reflects the information of the current load module.

Therefore, the program dictionary creating apparatus of the present invention includes a compiler that compiles a source program into object modules, a program dictionary registration means, and a program dictionary, and It is characterized by collecting information about data items, records, and files used by a program at compile time, and the dictionary registration means registering such information in the program dictionary.

Further, the method of creating a program dictionary of the present invention, the name of the data item used by each of the plurality of source programs, the name of the record to which the data item belongs, the name of the file to which the record belongs, and the data item above. A method for creating a program dictionary in which the name of a source program to be used is registered, in the process of compiling each source program, the name of the data item used in the source program and the record to which the data item belongs The name of the file, the name of the file to which the record belongs, and the name of the source program are extracted and stored in an intermediate file, and the contents of the intermediate file are registered in the program dictionary.

FIG. 1 is a block diagram of an embodiment of the present invention, FIG. 2 is a diagram showing a part of a program written in Kobol, and FIG. 3 is a block diagram of an embodiment of a search portion of a program dictionary. .

In FIG. 1, 1 is a source program, 2 is a compiler, 3 is a character string analysis means, 4 is a syntax analysis means, 5 is a code generation means, 6 is an object module, 7 is a linkage editor, and 8 is a load file. Module, 9 is an intermediate file, 10 is a program dictionary registration means, 11 is a program dictionary, and 12 is a pointer.

The source program 1 on the card or DASD is converted into an object module 6 by the compiler 2 and then into a load module 8 by the linkage editor 7. The compiler 2 has a character string analysis unit 3, a syntax analysis unit 4, a code generation unit 5, and the like. The program name, file name, record name and data item name of the source program 1 are extracted by the syntax analysis means 4 of the compiler and stored in the intermediate file 9.

FIG. 2 shows an example of a program written in Kobol. In FIG. 2, the program name is PROG102A, and this program is ITEM1021 of the record called REC102F in the file called F-MASTER. Using the data item called ITEM1022 and the G-MAST
It indicates that the data item called ITEM1023 and the data item called ITEM1024 in the record called REC102G in the file called ER are used.

Source program 1 has a file name as shown in Fig. 2,
When the record name and the item name are written, the data shown in the figure is written in the intermediate file 9. The program dictionary registration means 10 registers the contents of the intermediate file 9 in the program dictionary 11.

In program dictionary 11, for each data item used by multiple programs, the name of the record to which the data item belongs, the name of the file to which the record belongs, and the name of the program that uses the data item are written. . The program dictionary 11 is provided with a pointer 12, which points to the final data write position.

As shown in Fig. 1, when the source program called PROG101A and the source program called PROG101B have been compiled, the program dictionary 11 contains "PROG101A B-MASTER REC101B ITEM1011" or "PROG101B E-MASTER". REC101E ITEM1016 "is registered, and pointer 12 is" PROG101B E-MASTER REC101E ITEM
It points to "1016".

At the time when the compilation of the source program called PROG102A is completed, the data called "program name PROG102A" indicating the program name in the intermediate file 9 and "F-MASTER REC10" indicating the file name, record name, and data item.
Stores data such as "2F ITEM 1021" to "G-MASTER REC 102G ITEM 1024".

The program dictionary registration means 10 edits the data as shown in the figure stored in the intermediate file 9,
"PROG 102A F-MASTER REC 102F ITEM 1021" or "PROG
102A G-MASTER REC102G ITEM 1024 ”in the program dictionary 11. When this registration is completed,
Pointer 12 is "PROG 102A G-MASTER REC 102G ITEM 1024"
Point.

FIG. 3 shows an example of a search system using the program dictionary 11, 13 is a program
Control means for accessing the dictionary 11, 14 is a display, and 15 is a printer. The control means 13 has an interactive search function and a document output function. For example, when the operator specifies a data item name from the keyboard (not shown) of the display 14 and requests that the name of the program using this data item be displayed and output, the control means 13 causes the program dictionary 11 Is output and the name of the corresponding program is output on the display 14. When the operator requests that the display content be printed, the display content is printed out by the printer 15. Program Dictionary 11
Can search using not only data item names but also program names, file names, and record names as keys.

As is clear from the above description, according to the present invention, in the process of compiling a source program, the source
The name of the data item used in the program, the name of the record to which the data item belongs, the name of the file to which the record belongs, and the name of the source program are extracted, and the extracted information is registered in the program dictionary. In principle, a level mismatch cannot occur, and the effect that the search result of the program dictionary always reflects the substance information is obtained.
