You can create synonyms for any DEC DATATRIEVE keyword. A synonym
       cannot be another keyword. Do not use the same name for a keyword
       and for the name of a domain, record, field, or other name.

       To set up synonyms use the DECLARE SYNONYM command. The format
       is:

            DECLARE SYNONYM {synonym [FOR] keyword} [,...]

       For example:

       DTR> DECLARE SYNONYM PR FOR PRINT, E_S FOR EDIT_STRING

       The synonyms remain in effect until you terminate your session or
       until you release them with the RELEASE SYNONYM command. If you
       want to define synonyms for every DEC DATATRIEVE session, include
       a DECLARE SYNONYM command in your DTR$STARTUP file.

       To see which synonyms are in effect in your DEC DATATRIEVE
       session, type SHOW SYNONYMS.

       You can declare multiple synonyms for a single keyword by using
       multiple DECLARE commands.

       To release a synonym for your current session, type RELEASE
       SYNONYM followed by the name of the synonym.
