      $

      Example of a PATCH/ABSOLUTE/NONEW_VERSION command. Note the
      error messages that are returned when the command tries to
      expand the file, and when the commands UPDATE and EXIT are
      performed, that is, (file) "being overwritten."

    3.$ PATCH AVERAGE /JOURNAL=TEST /OUTPUT=TEST

      This command invokes PATCH for an interactive PATCH session
      with the image file AVERAGE.EXE. The journal file and output
      image file created by this session are both named TEST and
      reside in the default device and directory. The journal file
      has a file type of JNL, and the output image file has a file
      type of .EXE.

    4.$ PATCH /UPDATE=(100,102) @ORION
      $

      This PATCH command executes the command procedure ORION.COM.
      The /UPDATE qualifier requests that only the patches identified
      by the ECO levels 100 and 102, contained in ORION.COM, be
      processed. The first record in ORION.COM must specify the
      input image file. The second DCL prompt ($) indicates that
      the patches were successfully applied.
