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
