PROGRAM CONTROL DEVICE

PURPOSE:To reduce the number of controlling manhours and to remove defective control by relating a program object module source library to its updating history, coupling the object module to form an execution program at the execution of the program. CONSTITUTION:Program constitution information 9 and program control information 10 are read in the program object module source library and registered in a program constitution information file 3. Respective component control information in a program information file 5, respective member control information in the file 3 and members in the file 3 are chained on the basis of the information 9. At the execution of the program, a load module is coupled with the program from the program constitution information 9 to form an execution program library. Consequently, the number of processes of control is reduced and the generation of defective control is prevented.
