The SET TASK command enables you to establish the visible task
    and the active task, control the execution of tasks, and cause
    task state transitions, directly or indirectly.

    To determine the current state of a task, use the SHOW TASK
    command. The possible states are RUNNING, READY, SUSPENDED, and
    TERMINATED.
