CBIBK Prolog

 Name       : HCPCBIBK
 Description: Control Block Identifiers and Lengths
              Mapping
 DSECT      : CBIBK
 Function   : Provides a map for a control block's
              information in the HCPCBI table.
 Located by : The location of HCPCBI and the offset into
              HCPCBI provided by the HCPGETST and HCPRELST
              macros
 Created by : This block is never created. It is used to map
              portions of the HCPCBI data area
 Deleted by : Never deleted
 Serialized : None (HCPCBI is only changed at
              initialization)
