2 and the library unit 203.

The header section 201 stores control information and relocatable address information. The control information includes a file identifier and the number of relocation items. A predetermined code indicating that the file is an executable file is stored in the file identifier. For example, in MS-DOS (registered trademark) which is one of the personal computer OSs, "MZ" in ASCII characters is an identifier indicating that it is an execution file.

Further, the number of relocation items stores the number of relocatable address information. The relocatable address information indicates the position of the relocatable address included in the execution unit 202 by the relative address of the interactive automatic programming system 200a. In FIG. 4, the relocatable address information 201a, 201 of the header portion 201
b indicates the positions of the relocatable addresses 202a and 202b of the execution unit 202 by relative addresses in the interactive automatic programming system 200a.

The execution unit 202 is the program body of the interactive automatic programming system 200a. In addition, a general-purpose function program stored in the library unit 203 is called as needed.

For such an interactive automatic programming system 200a, the program loading means 1 shown in FIG.
02 stores the interactive automatic programming system 200a in the second memory 103 in the following procedure. Here, the relocatable addresses 103a and 103b correspond to the relocatable addresses 202a and 202b, respectively.

First, the program loading means 102 uses the header section 2 of the interactive automatic programming system 200a.
01 is read into the second memory 103. At this time, the start address of the header portion 201 is AD1, and the end address thereof is (AD2-1). Then, the number of relocation items is acquired from the control information of the header section 201. Note that description will be made here assuming that the number of relocation items is “2”.

Next, the program loading means 102 is the execution unit 20 of the interactive automatic programming system 200a.
2 and the library unit 203 (hereinafter referred to as “load module”) are read into the second memory 103. At this time, the start address of the execution unit 202 is AD2. In FIG. 4, the addresses of the header section and the load module are continuous in the second memory 103, but they are not necessarily continuous.

Then, the start address AD of the execution unit 202
2 and the relocatable address information of the header unit 201, an address operation for converting a relative address into an absolute address is performed, and the relocatable address of the interactive automatic programming system on the second memory 103 is updated.

For example, relocatable address information 20
The relocatable address 103a on the second memory 103 is obtained from 1a, the start address AD2 of the execution unit 202 is added to the content of the relocatable address 103a, and the result is stored in the relocatable address 103a and updated. Similarly, the relocatable address information 201
The relocatable address 103b on the second memory 103 is obtained from b, and the start address AD2 of the execution unit 202 is added to the content of the relocatable address 103b,
The result is stored in the relocatable address 103b and updated.

In this way, the address arithmetic processing of the relocatable address is performed for the number of relocation items. Then, the interactive automatic programming system 200a on which the address calculation processing is performed is the CPU 31 of FIG.
