Operation

       THIS MODULE IS CALLED BY THE COMMAND ANALYSIS ROUTINE DMKCFM.
       INITIALLY THE PARAMETERS OF THE COMMAND ARE EXAMINED,  AND
       INDICATORS OR ADDRESSES STORED. THEN THREE PAGES OF SPOOL
       SPACE ARE RESERVED FOR THE DMPINREC AND DMPKEY1 AND 2 RECORDS.
       NEXT, THE ADDRESSES REQUESTED ARE DUMPED TO SPOOL SPACE, WHILE
       THE KEYS ARE SAVED AND A BIT MAP CREATED. AFTER ALL ADDRESSES
       ARE DUMPED, THE DMPINREC AND KEY RECORDS ARE BUILT. LAST, THE
       SPACES ARE FREED UP AND A RETURN IS ISSUED.
