Abstract
A program control system in a multitask environment to execute a plurality of programs in parallel. The system includes a program execution control device for controlling an execution of a plurality of programs, a first program and a second program which are mutually related, a subtask execution recognition device for recognizing a subtask execution command in the first program, and a resumption control device for resuming the first program in response to both a wait command in the first program and an end command in the second program of the task associated with the task of the first program. When the subtask execution command is recognized by the subtask execution recognition device while the first program is being executed, the second program is also executed. When the end command in the second program is detected while the first program is in a wait state under the wait command, the resumption control means allows the program execution control means to resume the first program.
