The following example shows how to delete two domain versions
       from your default dictionary:

       DTR> SHOW DOMAINS
       Domains:
         * YACHTS;4  * YACHTS;3  * YACHTS;2  * YACHTS;1

       The following example does not specify a version number, so DEC
       DATATRIEVE deletes the highest version, YACHTS;4.

       DTR> DELETE YACHTS;
       DTR> SHOW DOMAINS
       Domains:
         * YACHTS;3  * YACHTS;2  * YACHTS;1

       DTR> DELETE YACHTS;2;
       DTR> SHOW DOMAINS
       Domains:
         * YACHTS;3  * YACHTS;1
