PURPOSE:To simplify a control program and to shorten a processing time, by executing the program which is modified the content of program in an RAM area in matching with control processing which varies with option setting information. CONSTITUTION:A basic control program is transferred from an ROM2 where the basic control program is stored to an RAM3 during the initializing operation of program execution. Then, the option setting information is inputted from an input part 4 to the RAM3. The control program is allowed to modify itself in the area of the RAM3 in matching with the optional setting information. This modified control program is executed by a microprocessor 1 to carry out processing without any awareness of option setting. |
