 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)
 RELOCATION CONSIDERATIONS : None
