 NAME       : HCPPCDBK
 DESCRIPTION: PROCESSOR CONTROLLER DIAGNOSE DATA BLOCK
 DSECT      : PCDBK
 FUNCTION   : MAPS HARDWARE PROCESSOR CONTROLLER DATA BLOCK FOR A
              REQUESTED COMMAND.  USED TO PASS INFORMATION BETWEEN
              CP AND THE PROCESSOR CONTROLLER WHEN USING THE
              DIAGNOSE X'80' INTERFACE.
 LOCATED BY : PCRRDBKA  ADDRESS POINTER TO THE PROCESSOR CONTROLLER
              DATA BLOCK TO BE USED IN PROCESSING THE
              ASSOCIATED REAL REQUEST.
              PCSACTIV  ADDRESS POINTER TO THE PROCESSOR CONTROLLER
              DATA BLOCK FOR THE CURRENT ACTIVE REQUEST.
 CREATED BY : HCPRFG    WHEN BUILDING REAL PROCESSOR CONTROLLER REQUEST
              HCPSCP    WHEN BUILDING REAL PROCESSOR CONTROLLER REQU
 DELETED BY : HCPRFG    WHEN REAL PROCESSOR CONTROLLER REQUEST COMPLETE
              HCPSCP    WHEN REAL PROCESSOR CONTROLLER REQUEST COMPL
 RELOCATION CONSIDERATIONS : None
