Before you can invoke DEC DATATRIEVE in a DECwindows Motif
       environment, you must be running DECwindows Motif software on
       your workstation. You may also find that to run DEC DATATRIEVE
       software on your workstation, the following conditions should be
       met:

       o  The logical DECW$DISPLAY should be pointing to the node on
          which you want to display DEC DATATRIEVE.

       o  The logical DTR$NOWINDOWS must be undefined or be assigned a
          value other than true.

       o  The Security item of the Customize menu of your Session
          Manager window should recognize the node on which you want
          to display your DEC DATATRIEVE session.

       These are described in more detail in the DEC DATATRIEVE Guide to
       Interfaces or in the DECwindows Motif documentation.

       You can then invoke DEC DATATRIEVE with either of the following
       commands:

       o  The DCL command RUN SYS$SYSTEM:DTR32xx.EXE (where xx
          represents the 1- to 26-character suffix appended at
          installation). You can also use any symbols that you have
          already defined to represent this command.

       o  The DATATRIEVE command. This command takes the following
          format:

          DATATRIEVE  [qualifier [...]]  ["DATATRIEVE-command-string"]

          The optional qualifiers to the DATATRIEVE command include the
          following:

                      /INTERFACE = {DECWINDOWS}
                                   {CHARACTER_CELL}

          Specifies the display interface to be used by DEC DATATRIEVE.
          If your default environment is the command-line interface,
          then CHARACTER_CELL is the default. If your system is properly
          defined to invoke the DEC DATATRIEVE interface to DECwindows
          Motif, the default is DECWINDOWS. This qualifier is useful
          if you are working in a DECwindows Motif environment and
          you want to submit a DEC DATATRIEVE command procedure from
          a foreign command line. Normally if your system is defined
          to invoke the DECwindows Motif interface and you try to
          execute a DEC DATATRIEVE command from a foreign command
          line, the DEC DATATRIEVE main application window appears on
          your screen. By using the DCL DATATRIEVE command with the
          /INTERFACE=CHARACTER_CELL qualifier, you can enter the command
          on a foreign command line and the main application window will
          not be displayed.

           /[NO]DEBUG

          Specifies whether DEC DATATRIEVE should display special debug
          messages. The default is NODEBUG.

          /VARIANT = image-suffix

          Indicates the 1- to 26-character suffix applied to a DEC
          DATATRIEVE image upon installation to uniquely identify that
          image. This qualifier is needed only if you invoke a DEC
          DATATRIEVE image that was not selected as the default image
          at installation time. If the default image you are running
          includes a suffix and you want to run an image that does not
          include a suffix, use the /VARIANT qualifier alone, as in the
          following example:

          $ DATATRIEVE/VARIANT

       The DCL DATATRIEVE command can also take a DEC DATATRIEVE command
       or statement as an argument. This allows you to execute a DEC
       DATATRIEVE command, statement, or procedure without entering
       interactive DEC DATATRIEVE. If the DATATRIEVE-command-string
       contains more than one word, it must be placed in quotation
       marks.

       You can abbreviate the DCL DATATRIEVE command to the shortest
       form that is unique among other DCL commands.
