0000    0 Structure      NSCPR          HCPNSCPR parameter list mapping
                   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.
                     THE INPUT FOR NSCSNTBK, NSCLSNT@, AND
                     NSCLNAME  ARE FILLED IN BY HCPNSC MODULE
                     AND SHOULD NOT BE FILLED IN BY THE CALLER.

                                        NAME.

                                          CONTINUE SEARCHING.
