ABSTRACT:
A data processing system operates in a multiprogramming mode in which a plurality of different tasks are performed, at least one of the tasks being interruptable by another one of the tasks, and the system includes at least one facility which is not used by all of the tasks. The method of operating the system includes the steps of permitting access to the facility by a first task requesting such access, detecting the interruption by a second task of the first task prior to completion of the first task's use of the facility, and preventing access to the facility by any task until the data and state information in the facility relative to the first task has been stored outside the facility.
