PROBLEM TO BE SOLVED: To select a work indicated by means of a master program without a mistake through the use of a slave program by permitting the master program to update work information to select only a specified processing object by means of the slave program. SOLUTION: The control program of a project controller 13 constitutes the master program for managing the operation of an application program and the application program such as a supervisor 2A and a video encoder 3A constitutes the slave program managed by the master one. Then the extender ord of an order file is re-written into the extender ctl as necessary so that the slave program detects that a project by the order file where the extender is not re-written is an execution possible processing. Thus, each slave program is successively started by the master program and executes the processing recorded in project information.
