IBMBERR*
IBMBERR identifies errors or condition codes during execution time, and performs the appropriate action based on the conditions.
IBMBERR has three entry points:
-
IBMBERRA - handles program check interrupts.
-
IBMBERRB - handles conditions and errors detected by code.
-
IBMBERRC - handles program check interrupts while control is in IBMBERR, modules it calls, or some housekeeping functions.
