   DTM> MODIFY GROUP MARGINS/REMARK="All border tests"
   _Remark:Replacing remark for group MARGINS
   %DTM-S-MODIFIED, group MARGINS modified
   DTM>

   This example replaces the existing remark associated with the
   group MARGINS with the remark "All border tests." It also logs
   the remark "Replacing remark for group MARGINS" with the MODIFY
   GROUP command in the history file.
