     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)
