To automatically perform selection of correction program according to an internal memory capacity and a size of correction program in a microcomputer system expanding and executing a program stored in a ROM on a RAM.
Correction priority 206 is independently given to correction programs 208 stored in the ROM. When program correction is executed, the correction program storable capacity 212 of the RAM is automatically determined, integration of program size 207 is performed in descending order of the correction priority 206 and in ascending order of the program size 207, the integrated value is compared with the correction program storable capacity 212, and correction programs 208 having high correction priority 205 within the range where the integrated value of the correction program size does not exceed the capacity 212 are selectively expanded on the RAM in ascending order of the correction program size 207.
