Abstract

PURPOSE:To suppress unnecessary translation by providing an object program output means, comparing generation information on a source program with that on an object program, and outputting only a necessary object program. CONSTITUTION:A source program generation reference means 10 refers to pieces of generation information on source programs 2-4 to be translated and stores them in a generation information storage means 11. Further, an object program presence confirming means 3 confirms whether or not there are object programs 7-9 and when not, that is reported to a translating means 5. Then an object program generation information reference means 14 refers to the programs 7-9 and stores generation information on an object program information storage means 15. Here, the pieces of generation information in the storage means 11 and 15 are compared with each other and an object program output means 16 indicates whether an object program needs to be outputted to the means 5. The means 5 instructs the addition of the generation information on the object program outputted to an object program generation information adding means 12. Consequently, the means 5 outputs only the object programs 7-9 necessary for translation, so unnecessary processing is suppressed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a target program output instruction method, and in particular, compares generation information of a source program with generation information of a target program at the time of translation to determine whether or not the target program is output. This invention relates to a method for instructing the output of a target program by determining the target program and instructing the translation means.

[Conventional technology]

Conventionally, in this type of target program output instruction method, when a job stream is created and executed using a job control language in order to create one executable program by translating and combining multiple source programs, , unless the user gave an instruction to stop outputting the target program during translation, all source programs were translated and the target program was output.

[Problem to be solved by the invention]

In the conventional target program output instruction method described above, when a job stream is created and executed using a job control language, all source programs are always translated and the target program is output, so only one source program is output. Even if the job stream is modified, if the job stream is executed without being rewritten, source programs other than the modified source program will also be translated and the target program will be output.
It has the disadvantage of wasting U (central processing unit) time.

In view of the above-mentioned points, an object of the present invention is to make it possible to output only the target program corresponding to the modified source program without rewriting the job stream when some of the source programs are modified. To provide a target program output instruction method capable of suppressing the output of a target program and saving CPU time.

Next, the operation of the target program output instruction method of this embodiment configured as described above will be explained.

Now, in an information processing system, when source programs 2.3 and 4 are created, their generation information becomes "1", and each time they are modified, "1" is added to the generation information. Immediately after the creation of source program 4, it is translated once by translation means 5 in the job stream, and if target programs 7.8 and 9 corresponding to source programs 2.3 and 4 have been created, for example, if source program 4 is modified and then Consider the case where translation is performed by the translation means 5 in a job stream.

When translating the source programs 2.3 and 4, the translation means 5 activates the source program generation information reference means 10.

The activated source program generation information reference means 10 reads the source program headers 2 of source programs 2.3 and 4.
1. Source programs 2゜3 and 4 in 31 and 41
In step 1o1), the source program generation information storage means 11 is activated.

The source program generation information storage means 11 activated by the source program generation information reference means 10 stores generation information of source programs 2, 3, and 4 (step 111).
).

When the generation information of the source programs 2, 3 and 4 is stored in the source program generation information storage means 11, the translation means 5 next activates the target program existence II recognition means 13.

The activated target program existence confirmation means 13 checks the target programs 7, 8 and 9 corresponding to the source programs 2, 3 and 4 which the translation means 5 is trying to translate, respectively.
Step 131 to check if already exists.
), if the target program generation information reference means 14 already exists (step 132 ); if the target programs 7.8 and 9 do not exist, the target program existence confirmation means 13 instructs the translation means 5 to refer to the target program generation information; Direct the output of programs 7.8 and 9 (step 13
3).

Here, since the target programs 7, 8 and 9 already exist, the target program existence confirmation means 13 activates the target program generation information reference means 14.

The target program generation information reference means 14 activated by the target program existence li1 verification means 6 13 reads the target program headers 71 and 81 of the target programs 7.8 and 9.
In step 141''), the target program generation information storage means 15 is activated.

The object program generation information storage means 15 activated by the object program generation information reference means 14 stores generation information of object programs 7.8 and 9 (step 15).
1).

When the generation information of the target programs 7, 8 and 9 is stored in the target program generation information storage means 15, the translation means 5 activates the target program output instruction means 16.

The activated target program output instruction means 16 first
The generation information of the source program 2 stored in the source program generation information storage means 11 is compared with the generation information of the target program 7 stored in the target program generation information storage means 15 (step 161 ), and the generation of the source program 2 is compared. If the information is larger than the generation information of the target program 7 (if the generation information of the source program 2 is newer than the generation information of the target program 7), the translation means 5 is instructed to output the target program 7 (step 16).
2) Conversely, if the generation information of the source program 2 is not larger than the generation information of the target program 7 (if the generation information of the source program 2 and the generation information of the target program 7 are equal), the translation means 5 uses the target program. 7 is not output (step 163).

The target program output instruction means 16 outputs the source program 3.
Regarding the generation information of and the generation information of objective program 8,
Also, generation information of source program 4 and target program 9
The same process as above is performed for the generation information.

Here, since the generation information of the source programs 2 and 3 is equal to the generation information of the target programs 7 and 8, the target program output instruction means 16 instructs the translation means 5 not to output the target programs 7 and 8. . On the other hand, since the source program 4 has been modified once, the generation information of the source program 4 is "1" larger than the generation information of the target program 9, so the target program output instruction means 16
instructs the translation means 5 to output the target program 9.

The translation means 5 does not output the target programs 7 and 8, but activates the target program generation information adding means 12 when outputting the target program 9.

The activated target program generation information addition means 12 references the generation information of the source program 4 stored in the source program generation information storage means 11 (step 12).
1) Instructs the translation means 5 to add the generation information of the source program 4 to the target program 9 as the generation information of the target program 9 (step 122).

The translation means 5 adds the generation information of the source program 4, which has been instructed to be added by the object program generation information adding means 12, to the ladder 91 as the generation information of the object program 9 to the object program of the object program 9, and Output.

〔Effect of the invention〕

As explained above, the present invention provides a method for creating a job stream in order to translate and combine multiple source programs to create one executable program and execute the job stream using a job control language. When re-translating some of the source programs that have been modified, the generation information of the source program is compared with the generation information of the target program, and if the generation information of the source program is newer, the target program is added to the translation means. By instructing the translation means not to output the target program otherwise, it is possible to output only the target program corresponding to the modified source program without rewriting the job stream. This has the effect of suppressing the output of the target program and reducing wasted CPU time.
