PROBLEM TO BE SOLVED: To provide a controller for a machine tool that can facilitate selection of a target machining main program from a storage means storing machining programs. SOLUTION: A search and analysis of machining programs stored in the storage means discriminates whether the machining programs are machining main programs. In the discrimination, machining programs with a program end code "M30" that is present in machining main programs are set as machining main programs. Alternatively, machining programs, without a machining subprogram end code "M99", are set as machining main programs. Machining main programs are found automatically and displayed in a list. Since machining main programs can be displayed without management, selection of a target machining program is facilitated. COPYRIGHT: (C)2008,JPO&INPIT
