Summary:PROBLEM TO BE SOLVED: To provide a controller capable of properly operating a provided subroutine program, even when the subroutine program provided in a main program is formed to be operative or non-operative under any conditions. SOLUTION: The controller has the main program, and the subroutine program which is called for execution by a subroutine branch instruction described in the main program. First, the subroutine program is initiated irrespective of satisfaction or non-satisfaction of an execution condition of the subroutine branch instruction. Further, in a variable memory, the information of satisfaction or non-satisfaction of the execution condition is stored and retained. When executing the subroutine program, the operation is determined according to the execution condition stored and retained above. COPYRIGHT: (C)2005,JPO&NCIPI
