/sys$common/syshlp/helplib.hlb MMS, Qualifiers, /FORCE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    /FORCE
    /NOFORCE(D)

    Controls whether MMS executes the action lines necessary to
    update one specific target. These qualifiers affect the behavior
    of MMS but not the execution of action lines.

    When you specify the /FORCE qualifier, MMS does not check whether
    the target or its sources are up-to-date, but simply rebuilds the
    specified target by executing the action lines. MMS also executes
    any .FIRST and .LAST directives associated with the target.

    The /FORCE qualifier is useful for quickly rebuilding a single
    target.
