VMS Help RMS, RMS Control Block Macros, $RAB STORE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

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