; DEFINE THE FOLLOWING SYMBOL TO HAVE ALL DUMPS NAMED

; CORE.DMP. DEFINING THE SYMBOL WILL TAKE MORE ADDRESS SPACE.

; DEFINE THE FOLLOWING SYMBOL TO DUMP ABORTING TASKS' READ-

; NOT BE DUMPED. THE SYSTEM TABLES WILL BE DUMPED ANYWAY.
; THIS IS NORMALLY ONLY INTERESTING IF STRANGE HARDWARE

; INST TRAP" ABORTS AND NOT AS SYSTEM CRASHES OR ERRORS.
