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)
