Translation information storage areas 22-1 to 22-m in which translation information 22-1' to 22-m' are stored, and translation information 22-
1' ~ 22-m' is the original program 21-1° ~ 2
A directory area 23 is provided in which information indicating which one of 1-n' corresponds to is stored. Each pre-translation 622-1' to 22-m' is information indicating the compiler's internal resources (memory size, work file capacity, etc.) required when translating the corresponding source program, and the source program 21- 1 from 1" to 21-n'
There is a one-to-one correspondence.

Referring to FIG. 2, the translation information checking means 11 refers to the directory area 23 in step 321 to check whether translation information corresponding to the source program specified by the translation instruction exists in the library file 2. In the next step S22, it is determined whether translation information corresponding to the source program specified by the translation instruction exists in the library file 2.

Referring to FIG. 3, the translation information area securing means 12 performs processing to secure a translation information storage area in the library file 2 in step 331, and in the next step 332, the translation information storage area is newly secured in the directory area 23. Stores information indicating the correspondence between the translation information stored in the source program and the source program.

In step S73, it is determined whether the capacity of the work file required for the current translation process is the same as that for the previous translation process, and if it is determined that it is different, the memory required for the translation is stored in step S72. After changing the information indicating the size to the memory size required for the current translation process, the process of step 373 is performed. If it is determined in step 373 that they are different, step 3
In step 74, the information indicating the capacity value of the work file necessary for translation is changed to the capacity value of the work file required in the current translation process. If other resources are secured by the translation environment setting means 15, the same processing as described above is performed on the information regarding the other resources in steps after step S74.

Next, the operation of this embodiment will be explained with reference to each figure.

When a translation instruction specifying the source program in the library file 2 is added, the compiler 1 passes control to the translation information checking means 11. When the translation information checking means 11 is given control, it refers to the directory area 23 in the library file 2 (step 521) and checks whether translation information corresponding to the source program specified by the translation instruction exists in the library file 2. (Step 522).

If it is determined that the translation information does not exist in the library file 2 (the determination result in step 322 is No), control is passed to the fixed translation environment setting means 18, and if it is determined that the translation information exists (the determination result in step 322 is is YE
In the case of S), control is passed to the translation information input means 14.

When the fixed translation environment setting means 18 receives control from the translation information checking means 11, it sets the operating environment of the translation processing means 17 based on preset default values or values given by the user, and performs translation processing. Control is passed to means 17.

Furthermore, when the translation information input means 14 receives control from the translation information inspection means 11, it performs an open (input mode) process for the library file 2 (step 351), and then translates the source program specified by the translation instruction. Step 352: Enter information from library file 2. 353), then closes the library file 2 (step 554), and then passes control to the translation environment setting means 15. Translation environment setting means 15
When control is passed from the translation information input means 14, step 361. secures the memory size and work file capacity necessary for translation based on the translation information input by the translation information input means 14. 362), if other resources are required, by securing other necessary resources,
The operating environment of the translation processing means 17 is prepared, and then control is passed to the translation processing means 17.

When the translation processing means 17 receives control from the translation environment setting means 15 or the fixed translation environment setting means 18, it inputs the source program specified by the translation instruction from the library file 2, performs translation processing, and generates the target program. . The translation processing means 17 is a fixed translation environment setting means 18
If control is passed from , that is, if translation information corresponding to the source program specified by the translation instruction does not exist in the library file 2, control is passed to the translation information area securing means 12 after generating the target program. If the translation environment setting means 15 issues translation information, that is, if translation information corresponding to the source program specified by the translation instruction exists in the library file 2, the translation information replacement is performed after generating the target program. Control is passed to means 16.

When the translation information area securing means 12 receives control from the translation processing means 17, it secures a translation information storage area in the library file 2 for storing the translation information of the source program to be translated this time (Step 531), and then Information indicating the correspondence between the source program to be translated this time and its translation information is stored in the directory area 23 (step 532), and then control is passed to the translation information output means 13.

When the translation information output means 13 is given control, it performs oven (output mode) processing on the library file 2 (step 541), and stores the current translation information in the translation information storage area secured in the library file 2 by the translation information area securing means 12. In step S42. 543), and then close processing of library file 2 is performed (step 544).

Further, when the translation information replacement means 16 is given control from the translation processing means 17, the memory size required for the current translation processing is the same as that of the previous translation of the source program for which the translation processing was performed this time. It is determined whether the memory size is the same as the memory size required for the process (the memory size indicated by the translation information corresponding to the source program) (step 571), and if it is determined that they are the same (step S71). If the judgment result is YES), perform the process of step 373, and if it is judged that they are different (if the judgment result of step 371 is No), the part indicating the memory size of the above translation information is included in the current translation process. Then, the memory size is changed to the required memory size (step 372), and then the process of step S73 is performed. In step 373, the capacity of the work file required for the current translation process is equal to the capacity of the work file required for the previous translation process for the same source program as the source program for which the current translation process was performed. (The capacity of the work file indicated by the translation information corresponding to the source program) is determined. and,
If it is determined in step S73 that they are the same (if the determination result in step S73 is YES), the process ends; if it is determined that they are different (if the determination result in step S73 is NO), the above translation information is , change the part indicating the capacity of the work file to the capacity value of the work file required in the current translation process (step 574).
. If the translation information includes information about other resources, the same processing as described above is performed on each piece of information in steps after step S74. Here, the judgment results in steps S71 and S73 are NO because:
This is a case where the source program to be translated this time has been corrected compared to when it was translated last time, so even if the source program in library file 2 is corrected by performing the above processing, The translation information in the library file 2 can be made compatible with the latest source program.
