/sys$common/syshlp/helplib.hlb DTM, DELETE, HISTORY, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   DTM> DELETE HISTORY /BEFORE=08-JAN "Deleting old information"
   Confirm DELETE HISTORY/BEFORE=8-Jan-1998 [Y/N] (N): Y
   %DTM-S-HISTDEL, 150 history records deleted
   DTM>

   This example deletes all history records in the history file
   recorded before January 8, 1998. The deleted information is
   replaced with the following record:

   * 8-JAN-1998  00:00:00 SMITH REMARK  "PREVIOUS HISTORY DELETED"
