CANCEL taskname The CANCEL command cancels time-based initiation requests for a task. These requests result from a RUN$ directive or any of the time synchronized variations of the DCL RUN command. A CANCEL command directed to a task not initiated from the entering terminal can only be issued from a privileged terminal. CANCEL does not affect the execution of the task while it is currently active. CANCEL removes only the time-based schedule requests still in the queue.
