Abstract

PURPOSE: To shorten the search time for calling of a subroutine, by arranging a subroutine call instruction for the subroutine formed by combination of program instructions.
CONSTITUTION: The program type computer which has many kinds of program instruction and performs various operations, control and so on according to combinations of these instructions is provided with CPU part 1 which controls the whole of the device. Input part 2 dependent upon the keyboard and so on and output part 3 dependent upon the printer and so on are connected to CPU part 1, and further, program memory part 4 storing the program is connected to CPU part 1 through program counter part 5. Program set part 6 is connected to memory part 4, and subroutine call deciding part 7 is connected between set part 6 and CPU part 1 to make it possible to decide whether contents of set part 6 are a subroutine call instruction or not. Thus, the search time for calling of the subroutine in execution of the main program is shortened.
