ABSTRACT:
A plurality of trap save areas are linked to form a pool of such areas from which an area may be loaded with context from various sources in response to a trap condition, such as the addressing of unuseable memory, the loaded area unlinked from the pool, and various pointers changed to reflect such unlinking. The unlinked area is associated with the process which was executing at the time of the occurrence of the trap condition by effectively being coupled to the interrupt level of such process. Independent of the interrupt level, a trap handler routine, specific to the nature of the trap condition, is executed following which the unlinked area is returned to the pool and the various pointers changed to reflect such return.
