VMS Help DTM, MODIFY, GROUP, Command Qualifiers, /REMARK  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   /REMARK="string"
   /NOREMARK

   Specifies whether to replace or delete the remark associated
   with the group. This remark is associated with the group you
   are modifying; it is not the remark logged with the MODIFY GROUP
   command.

   The /REMARK qualifier adds the specified remark to the group. This
   string replaces any previous remark associated with the group. The
   /NOREMARK qualifier deletes the remark from the group.
