VMS Help MMS, FMS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    If FMS (Forms Management System) is installed on your system, you can
    use MMS to access forms stored in FMS libraries.  To specify   an FMS
    form  in a  dependency  rule,  use the  same syntax  as for  files in
    OpenVMS libraries.  The file type .FLB after the library name informs
    FMS that the library contains FMS forms.  The default file  type  for
    FMS forms is .FRM.

    The  MMS  default  macro  FMSFLAGS  invokes  FMS  with  the  /REPLACE
    qualifier.

    MMS uses the insertion time of a form in an FMS library to  determine
    whether  a  source  is  newer  than  the  target.  You cannot use the
    /REVISE_DATE qualifier with references to FMS forms.
