PURPOSE:To improve the processing efficiency of a process by providing the titled system with a suspension record for storing the leading and final values of a process queue queuing concrete value every variable and the leading and final values of a process queue queuing another variable. CONSTITUTION:The suspension record having two queues every variable, e.g. a variable X, is formed and the leading and final values of a process queue queuing a concrete value and the leading and final values of a process queue queuing another variable are respectively stored in the record 10. When the concrete value is written in the variable X having the record 10 under said status, a suspending lists Q1H, Q1T having concrete values and suspending lists Q2H, Q2T having another variables are resumed. When another variable is written in the variable X having the record 10, only the suspending lists Q2H, Q2T of other variable is resumed. Consequently, the process can be efficiently executed. |
