ABSTRACT:
A relocator (4a) is appended to an executable program (4) for checking program information and the size of a memory area in the memory (25). This program (4) is then stored in the file storage unit (1) as a file. When the user starts the CPU (24) with the keyboard (27), the file is stored in the memory (25) as a program. Where another executable program (9) is stored in the memory (25) at the fixed address under these conditions, the relocator-appended executable program (4) is relocated and restored at the address which is specified by the information of the relocator (4a) and, then, the other executable program (9) is stored in the fixed address.
