 NAME       : HCPCNUBK
 DESCRIPTION: USER DATA MAPPING FOR *IDENT
 DSECT      : CNUBK
 FUNCTION   : PROVIDES A MAPPING OF THE USER DATA AREA PASSED
              BY A VIRTUAL MACHINE (AUTHORIZED TO IDENTIFY/REVOKE
              A PARTICULAR RESOURCE/GATEWAY) TO THE *IDENT SYSTEM
              SERVICE DURING CONNECT PROCESSING.
              NOTE THAT THE FIRST X'10' BYTES OF THE CNUBK MAP TO
              IPUSER IN THE IPARML.  THIS AREA SHOULD NEVER CHANGE.
 LOCATED BY : IPUSER IN THE IUCV/APPC PARAMATER LIST (IPARML),
              UNLESS CREATED BY ISFC.
 CREATED BY : CONNECTING VIRTUAL MACHINE OR ISFC.
              NOTES      : When adding fields to the CNUBK, 8 bytes
              must be added at a time. This is because
              the CONBK includes a CNUBK and specifies
              its length in terms of doublewords.
 DELETED BY : CONNECTING VIRTUAL MACHINE OR ISFC.
 SERIALIZED : NONE.
