NSCPR Prolog
Name : HCPNSCPR Description: Parameter list for HCPNSCSG and HCPNSCSY. DSECT : NSCPR Notes : - A first time search requires only that NSCNAME be filled in. - A second-time search or a re-scan requires NSCSNTBK be filled in for NSS, DCSS, SEGMENT SPACE, and members. For member segments NSCLSNT@ and NSCLNAME need to be filled in to determine if the member is still part of the segment space. - 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.
