PROGRAM CONTROL METHOD, PROGRAM EXECUTION METHOD AND COMPUTER READABLE RECORDING MEDIUM

PROBLEM TO BE SOLVED: To simplify and clarify the constitution of a main program to be complicated and scale-enlarged as functions to be realized are increased by executing plural sub-routines in a prescribed order by the start address of the sub-routine developed in the stack memory of a system by a processing task unit. SOLUTION: In a control program operated in a computer, the plural sub- routines are executed in the prescribed order by the start address of the sub-routine developed in the stack memory of the system by the processing task unit. When a state to process a processing task A is attained, a main program 1 sets the leading address of the TBL-A of a processing task table 2 for realizing the function of the task A to an argument with a registration program 4 and activates the registration program 4. The registration program 4 performs processings for the number of pieces of sub-routine addresses entered in the TBL-A and writes the addresses of the sub-routines 5 in the execution order in the stack memory 3.
