Note that if the program 4z is not a program to be executed in the personal computers 31 to 3n (NO in step SIO), the above processing is not performed.

On the other hand, if it is determined in step S5 that the program 4y read in step S3 is a program to be executed on the personal computers 31 to 3n (No in step S5), the program 4y is added to the already created program framework 61. (step 512), and then it is determined from the information already obtained whether or not the program 4y is called from a program executed on the host computer 1 side (step 513). If applicable (YES in step S13), the interface source language description 7 for making correspondence with the host computer 1
1 is generated and added to the source language image of the program 4y (step 514);
If the program is not called by a program executed on the side (No in step S13), the above process is not performed.Next, the program name item corresponding to the program 4z called by the program 4y is entered in the program correspondence table file 5. The program 4z is determined by referring to the program correspondence table file 5 (step 516), and it is determined whether the program 4z is a program to be executed on the host computer l (step 516). 1 (YES in step SL6)
), generates an interface source language description 72 for correspondence with the host computer 1, and executes the program 4y.
The program 4z is expanded into the program framework 61 by replacing the description for calling it (step 51).
