1.$ TYPE XXX
      %TYPE-W-OPENIN, error opening DB1:[MARSHALL]XXX.LIS; as input
      -RMS-E-FNF, file not found
         .
         .
         .
      $  SET MESSAGE/NOIDENTIFICATION
         .

         .
      $ TYPE XXX
      %TYPE-W, error opening DB1:[MARSHALL]XXX.LIS; as input
      -RMS-E, file not found

      When the first TYPE command is entered in this example, the
      error messages include all fields. Later, the SET MESSAGE
      command establishes that the IDENT portion (the abbreviation
      for the message text) is omitted in future messages.

    2.$ SET MESSAGE NEWMSG

      The SET MESSAGE command in this example specifies that the
      message text in NEWMSG.EXE supplements the existing system
      messages.
