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
