Abstract

PURPOSE: To realize the display for the unused program numbers by installing the program memory device to memorize the supplied program information plus the means to read the contents of the program memory device and then detect the program numbers which are already written.
CONSTITUTION: When the program is written, the address designation code signal of ROM32 is transmitted from the control part via address part 21 and with operation of key input part 10. And the program number is read out of ROM32 to be written into the X register of RAM25. Then the address of RAM 31 is designated, and the contents of the address is read out to the Y register of RAM25. A decision is given at operation/judge part 24 to the numbers already written in RAM31 among all program numbers which are set first to the X register, and the unused program numbers are sent to display driving circuit 33 to be displayed at display part 33. In such way, the same program number is never used mistakenly, thus avoiding the programing error.
