/sys$common/syshlp/helplib.hlb RMS, RMS Control Block Macros, $FAB STORE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The $FAB_STORE macro moves user-specified values into fields of
    the specified FAB. The expanded $FAB_STORE code executes at run
    time on a previously initialized (allocated) FAB, in contrast to
    the $FAB macro, which initializes the FAB at assembly time. The
    $FAB_STORE macro must reside in a code program section.
