1    /CONTINUOUS

       /CONTINUOUS (default)
       NOCONTINUOUS

          The /CONTINUOUS qualifier invokes a continuous
          monitor display. Entering Ctrl/C, Ctrl/Y, or Ctrl
          /Z terminates this display.

          Using /NOCONTINUOUS indicates the monitor process
          should provide a snapshot display and then exit to
          the DCL prompt.

2    /VOLUME

       /VOLUME (default)
       /NOVOLUME

          The /VOLUME qualifier indicates that a volume name
          instead of a script name is present on the command
          line. The /VOLUME qualifier must be used when a
          volume name is provided as a parameter to the MONITOR
          subcommand.
