CNUBK Prolog
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.
