              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.
