                       THESE FIELDS ARE USED FOR ENTRY TO HCPNSCSG
                 AND HCPNSCSY.
                 - FIRST TIME SEARCH ONLY REQUIRES THAT NSCNAME BE
                   FILLED IN.
                 - SECOND TIME SEARCH OR A RE-SCAN WOULD REQUIRE
                   NSCSNTBK TO BE FILLED IN FOR NSS, DCSS, SEGMENT
                   SPACE, AND MEMBERS.
                   FOR MEMBER SEGMENTS NSCLSNT@ AND NSCLNAME NEED TO
                   FILLED IN TO DETERMINE IF THE MEMBER IS STILL PART
                   OF THE SEGMENT SPACE.
                   NOTES      : NSCSNTBK IS FILLED IN BY BOTH ENTRY POINTS.
                         NSCLSNT@ AND NSCLNAME ARE FILLED IN BY
                         HCPNSCSG ONLY.

                         AND SHOULD NOT BE FILLED IN BY THE CALLER.
