PURPOSE:To preliminarily judge whether an execution program can be operated up to the end of operation or not by comparing system constituting elements used by the execution program and system constituting elements, which operates the program, with each other at the time of starting the program. CONSTITUTION:When a start command 1 is supplied, a program retrieving mechanism 2 retrieves an execution program 3 and reads in a header 31 including used system constituting element information 33 and stores it in a header storage area 4. A comparing mechanism 6 reads in information 33 and operated system constituting element information 5, which operates the execution program 3, from the area 4. It is decided whether all of system constituting elements which operate the execution program 3 are included there or not, and a body 32 of the execution program 3 is loaded by a loading means 7 to start the execution program 3 if they are included. If they are not included, error is reported to an operator by a reporting means 8 to terminate the processing.
