Abstract

PURPOSE:To execute exchange of a form, etc. before an input/output device is started over again by an operator, by providing in advance a nonready instruction as a microinstruction, and immediately stopping an opration of the input/output device when said instruction has been read out. CONSTITUTION:A nonready instructon is provided in advance as a microinstruction. An electronic cmputer 1 reads out an instruction from a main memory 2 by a regular method, and executes the procesing. Now, when the nonready instruction is stored in an instruction register 4, a decoder 5 generates a nonready signal 7, and energizes an AND circuit 8 designated by an input/output device designating part in the instruction register 4. A line printer 9 receives a nonready command 11 thrugh an interface 10. When the nonready signal is received, a latch 13 is set. A controlling circuit 12 chooses the timing and immediately stops the line printer 9, and makes it a nonready state. It becomes a wait state until an operator pushes a start switch 14 and it is started again.
