Abstract

PURPOSE:To always secure a fact that the retrieving result of a program dictionary reflects the information on a real matter, by always performing both compiling and dictionary registering jobs at a time. CONSTITUTION:A source program 1 is converted into an object module 6 by a compiler 2 and then into a load module by a linkage editor 7. For the program 1, the program name, the file name, the record name and the item name are extracted by a sentence structure analyzing means 4 and stored in an intermediate file 9. If the file name, record name and item name are written to the program 1 has shown in the figure, the data are written to the file 9. A program dictionary register part 10 registers the contents of the file 9 to a program dictionary 11. Then the relevant record names, the file names of these records and the program names using the corresponding data items are written to the dictionary 11 in terms of the data items to be used by plural programs. A pointer 12 points out the final writing position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system in which the name of a data item used by a program, the name of the record to which the data item belongs, the name of the file to which the record belongs, the name of the program that uses the data item, etc. It concerns the creation method of the embedded program dictionary.

Traditionally, compilers did not take care of cross-references between multiple programs. For this reason, for example, the length of the field ``Department Code'' can be set to 1.
If you want to increase the number of digits, to find out what program is accessing this field, use
I had to look at the source list or 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 that uses the data item are registered in a program dictionary. However, conventionally, the process of compiling a source program and the process of registering information in a program dictionary have been completely separate. Therefore, although the source program was compiled to create a load module, the information may not be registered in the program dictionary, or the opposite may occur and the program dictionary may not correctly reflect the current load module information. This will lead to a situation where they say they have not done so (at a different level). This has the disadvantage that the authenticity of the program dictionary is lost.

The present invention is based on the above considerations, and aims to create a program dictionary that accurately reflects current load module information.

Therefore, the program dictionary creation method of the present invention includes a compiler (2) that interprets a source program into an object program, a program dictionary registration means (10), and a program dictionary (11). , The compiler (2) collects information regarding data items, records, and files used by the program at the time of compilation, and the dictionary registration means (10) registers this information in the program dictionary (11). , and is characterized in that compilation by the compiler (2) and dictionary registration by the dictionary registration means (10) are executed as a series of processes. Hereinafter, the present invention will be explained with reference to the drawings.

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

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

A source program 1 on a card or DASD is converted into an object module 6 by a compiler 2, and then converted into a load module by a linkage editor 7. The compiler 2 includes a character string analysis means 3, a syntax analysis means 4, a code generation means 5, and the like. The program name, file name, record name, and 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. Figure 2 shows an example of a program written in Kobol, and the program name in Figure 2 is PROG10.
2A, this program records the data item ITEM1021 of the record REC102F in the file F-MASTER and the data item ITEM1021.
Using the data item E M1022, and G
-REC in the file called MASTER
This indicates that the data items ITEM1023 and ITEM1024 in the record 102G are used. When file names, record names, and item names as shown in FIG. 2 are written in the source program 1, data as shown in the figure is written in the intermediate file 9.

The program dictionary registration unit 10 registers the contents of the intermediate file 9 in the 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 in the program dictionary 11. There is. A pointer 12 is provided in the program dictionary 11, and this pointer 12 points to the final data writing position.

FIG. 3 shows an example of a search system using the program dictionary 11, in which 13 is a control means for accessing the program dictionary 11;
Reference numeral 14 indicates a display, and reference numeral 15 indicates a printer. The control means 13 has an interactive search function and a document output function. For example, when an operator specifies a data item name from the keyboard (not shown) of the display 14 and requests that the name of a program using this data item be displayed and output, the control means 11
searches the program dictionary 11 and outputs the name of the corresponding program on the display 14.

When the operator requests that the displayed content be printed out, the displayed content is printed out by the printer 15. The program dictionary 11 can be searched using not only data item names but also program names, file names, and record names as keys.

As is clear from the above explanation, according to the present invention, compilation and dictionary registration are always performed at the same time, so in principle, level mismatch cannot occur, and the program
The effect is that the dictionary search results always reflect the actual information.
