                  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.
         NOTE: NSCSNTBK IS FILLED IN BY BOTH ENTRY POINTS. NSCLSNT@ AND NSCLNAME
         ARE FILLED IN BY HCPNSCSG ONLY. THE INPUT FOR NSCSNTBK, NSCLSNT@, AND
         NSCLNAME ARE FILLED IN BY HCPNSC MODULE AND SHOULD NOT BE FILLED IN BY
         THE CALLER.
