PURPOSE:To shorten the job processing time by generating a job having the highest priority level and a job having the lowest priority level of a line number at the time of input of a forcible interrupt instruction to jobs of this line number from a higher-order device and queuing these jobs in a queue and indicating a forcible interrupt range between these jobs. CONSTITUTION:Generated jobs are queued in the priority level order and jobs having the same priority level are queued in the generated order as shown by 26. First, second-sixth generated jobs (1), (2)...(6) are arranged in the priority level order and the generation order and jobs (6), (1), (3), (5), (2), and (4) are arranged in order in the queue 26. When the forcible interrupt instruction to a line number 1 is inputted, a job (7) having the lowest priority level is generated and is queued at the trail of the queue 26. Then, the range of the forcible interrupt processing is between the first job (6) and the last job (7), and the forcible interrupt processing range is clarified by jobs (6) and (7). Jobs (1) and (2) related to the line number 1 in this range are not processed. Thus, the job processing time is shortened. |
