The DCL command DATATRIEVE starts a DEC DATATRIEVE session. This
       DCL command lets you specify several optional qualifiers that let
       you customize your DEC DATATRIEVE session.

       Format

                     [             {DECWINDOWS      } ]
                     [ /INTERFACE= {                } ]
         DATATRIEVE  [             {CHARACTER_CELL  } ] ["DATATRIEVE"]
                     [ /[NO]DEBUG                     ]
                     [ /VARIANT=image-suffix          ]
                     [                                ]

1  –  Arguments

    /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 DECwindows Motif interface, then DECwindows Motif
       is the default. This qualifier overrides the setting specified by
       the DTR$NOWINDOWS logical.

    /[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

    "DATATRIEVE"

       Specifies a DEC DATATRIEVE command or statement that is to be
       executed by DEC DATATRIEVE. It allows the user to execute a DEC
       DATATRIEVE command, statement, or procedure without entering
       interactive DEC DATATRIEVE. If the DEC DATATRIEVE argument
       contains more than one word, it must be placed in quotation
       marks.

2  –  Example

       The following example shows how to execute the DEC DATATRIEVE
       SHOW DICTIONARY command without entering interactive DEC
       DATATRIEVE.

       $ DATATRIEVE/INTERFACE=CHARACTER_CELL "SHOW DICTIONARY"

       The default directory is _CDD$TOP.DTR$LIB.DEMO

       $
