Cancels wakeup requests for a specified process, including wakeup
    requests scheduled with either the RUN command or the $SCHDWK
    system service.

    Requires one of the following:

    o  Ownership of the process

    o  GROUP privilege to cancel scheduled wakeup requests for
       processes in the same group but not owned by you

    o  WORLD privilege to cancel scheduled wakeup requests for any
       process in the system

    Format

      CANCEL  [[node-name::]process-name]

1  –  Parameters

 node-name::

    The name of the node on which the specified process is running.

    You cannot specify a node name on a different OpenVMS Cluster
    system from the current process.

 process-name

    The name of the process for which wakeup requests are to be
    canceled. The process name can have up to 15 alphanumeric
    characters.

    The specified process must be in the same group as the current
    process.

2  –  Qualifier

2.1    /IDENTIFICATION

       /IDENTIFICATION=pid

    Identifies the process by its process identification (PID). You
    can omit leading zeros when you specify the PID.

3  –  Examples

    1.$ CANCEL CALENDAR

      The CANCEL command in this example cancels a wakeup request for
      a process named CALENDAR (which continues to hibernate until it
      is deleted with the STOP command).

    2.$ RUN/SCHEDULE=14:00 STATUS
      %RUN-S-PROC_ID, identification of created process is 0013012A
         .
         .
         .
      $ CANCEL/IDENTIFICATION=13012A

      The RUN command in this example creates a process to execute
      the image STATUS. The process hibernates and is scheduled to be
      awakened at 14:00. Before the process is awakened, the CANCEL
      command cancels the wakeup request.

    3.$ RUN/PROCESS_NAME=LIBRA/INTERVAL=1:00    LIBRA
      %RUN-S-PROC_ID, identification of created process is 00130027
         .
         .
         .
      $ CANCEL LIBRA
      $ STOP LIBRA

      The RUN command in this example creates a subprocess named
      LIBRA to execute the image LIBRA.EXE at hourly intervals.

      Subsequently, the CANCEL command cancels the wakeup request.
      The process continues to exist, but in a state of hibernation,
      until the STOP command deletes it.
