Abstract: For a digital computer operating under a multilevel periodically occurring priority routine wherein information is transferable from a first field to a second field of a data store only during the lowest priority level, there is disclosed a method for updating information stored in the first field. The method contemplates preventing indiscriminate access to the first field. Instead, when during any level but the top priority level access is required to the first field for updating, the work being performed is interrupted and the computer switched to the top priority level. In this level, the updating information is simultaneously stored in corresponding locations of the first and second fields. Thereafter, the computer is restored to perform the interrupted work.
