SIMULATE A SERVICE CALL INSTRUCTION FOR A GUEST AND
FOR CP REQUESTS TO THE PROCESSOR CONTROLLER.
LOCATED BY :
R2 REGISTER OF A GUEST SERVICE CALL INSTRUCTION
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
REQUEST.
GUEST WHEN ACTIVATING A VIRTUAL SERVICE CALL
INSTRUCTION
DELETED BY :
HCPRFG WHEN REAL PROCESSOR CONTROLLER REQUEST
COMPLETE.
