The following are examples of invoking the monitor:

    1.$ DEFRAGMENT MONITOR MY_SCRIPT/NOVOLUME

      In this example, the monitor function displays ongoing run-time
      statistics for the defragmentation process associated with MY_
      SCRIPT. It also displays an approximate free-space map of the
      target volume. The display continues until interrupted with a
      Ctrl/C, Ctrl/Y, or Ctrl/Z because the /CONTINUOUS qualifier is
      present by default.

    2.$ DEFRAGMENT MONITOR DISK$ONE/NOCONTINUOUS

      In this example, the defragmentation process executing against
      DISK$ONE is monitored. Since the /NOCONTINUOUS qualifier was
      specified, the monitor function samples the defragmentation
      process statistics and the free space on DISK$ONE one time
      before exiting to the DCL prompt.
