     FUNCTION = DEFINE THE MAJOR BMS CONTROL BLOCK. THIS IS CHAINED
                OFF THE TCA SYSTEM AREA. IT IS BUILT BY DFHMCP ON
                THE FIRST BMS REQUEST IN A TRANSACTION, AND IS FREED
                AT TASK TERMINATION. LARGE PARTS OF THE OSPWA ARE
                CLEARED BY DFHMCP ON SEND PAGE.
