          Specifies the name of the report to produce.

          The report name should be the name of one of the Digital
          supplied reports or the name of a user-written report.  You
          can abbreviate the report name if the abbreviation is unique.

          The REPORT command uses this parameter to find a
          corresponding TPU procedure whose name starts with
          SCA_REPORT_report-name.  This TPU procedure is invoked to
          produce the report.  Because there is a TPU restriction on
          the length of procedure names, a report name must not exceed
          121 characters.

          Digital has implemented the following reports:

              o  HELP-A help file, suitable for processing by the
                 VMS Librarian into a help library.

              o  PACKAGE-An LSE package definition, which can be
