摘要

The execution state of an instruction which is input by an operator is detected and the process to detect an execution state of the instruction supervised so that when errors occur, errors are informed to the operator and an application program. The method comprises the steps of: (a) finding a job number corresponding to the input instruction and sending an operating instruction information to an application program; (b) standing by to receive an output message sent by an application program when the instruction is executed; (c) detecting the executing state for input instruction; and (d) sending time out of instruction to the operator and the application program.
