VMS Help DTM, @file-specification, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   DTM> @MAIL_TEST
   %DTM-S-LIBIS, Digital Test Manager library is DUA0:[USER01.DTMLIB]
   %DTM-S-RESUBMITTED, collection MAIL_TEST has been resubmitted
   -DTM-I-TEXT, Job MAIL_TEST (queue SYS$BATCH, entry 18) started on SYS$BATCH

   containing the commands SET LIBRARY DUA0:[USER01.DTMLIB] and
   SUBMIT MAIL_TEST.
