DU-AL

ESTAE-type recovery routines receive control with the DU-AL that was current at the time of the error, as modified by any previous recovery routines, with the following exception. For an ESTAE-type recovery routine activated by an IRB, or activated by an IRB's ESTAE-type recovery routine, the ESTAE-type recovery routine receives the IRB's DU-AL (IRBs get control with their own DU-AL). The system does not modify the contents of the DU-AL during recovery processing.
