The system utilizes processors monitoring the occurrence of particular processing events within a local memory storage area. Upon the detection of events indicating the change of status of a particular group of data, a comparison is made between a modified copy of the group of data and a clean copy of the group of data to detect any modifications made to the group of data. These modifications are entered into the clean copy of the group of data and processing continues.
