PURPOSE:To perform efficient programming, by making the instruction which can be returned to the next step to the jumped step without fixing the returned process through jump and allowing to execute these instructions over multiplex. CONSTITUTION:The instructions indicated in the table are set to programs S0-Sn, and the program of each step is sequentially read out by the process counter 208 and the process selector 202 for decoding 203. After decoding 203, the step number in which the JS instruction is programmed is written in the tentative storage area provided in the operation section 205. Thereafter the counter 208 is set to the jumped address indicated with the JS instruction, the program of the subroutine of the jumped address is selected by the selector 202 and connected to the decoding section 203. Thus, the program of the subroutine step of the jumped address is executed. When the RT instruction is decoded 203, the selector 202 selects the program of the next step to the step having the JS instruction, allowing to execute the program of the step after that. |
