PURPOSE:To eliminate the missetting of a switch and the troublesomeness of switching, by storing switch information for a program input and using this stored switch information for program execution to execute the program. CONSTITUTION:When a program is inputted, key data is inputted to a CPU23 from a key matrix 20 through a terminal J3 and is stored as a program in a RAM24 after the processing for key information. In this case, since a mode switch J9 is turned off, a high-level signal is led to NAND gates 21 and 22, and respective switch signals are transmitted to the CPU also for the program input and are processed and are stored in the RAM24. For program execution, the program stored in the RAM24 is called and is executed in the CPU23. Since the switch J9 is turned on, a low-level signal is led to gates 21 and 22, and respective switch signals are not sent to the CPU23, and thus, the program is executed independently of these switch states. |
