PURPOSE:To search a program in work units by searching a program stored in a numerical controller in accordance with not only a program number but also a part of the program name and outputting the program. CONSTITUTION:A numerical controller 1 has a microprocessor 10, and a ROM 1, a RAM 12, a non-volatile memory 13, a reader/puncher interface 14, a CRT display device 15, a keyboard 16, and a shaft control circuit 17 are connected to the controller 1 by a bus 18. The non-volatile memory 13 is provided with a program memory 13a and a program management table 13b. Various programs and their program names are registered and stored in the program memory 13a; and when a registered program name is inputted and a search command is inputted, the program memory 13a is searched to display all program names including this information.
