Abstract : UPDATE was written as an interim solution to the basic problem all data processing systems face in a real time environment: total loss of all unprocessed data during error-induced diagnostic recovery modes. It provides the user with a means of periodically updating the permanent drum copy of any data object from its core image, thus allowing a return from diagnostics to an operational environment with a minimal loss of data. UPDATE is part of the Automatic Operating and Scheduling Programs' (AOSP) repertory of service and utility routines for the AN/GYK-3(V) (Burroughs D-825) computer, and is available for use by all operational programs. The report includes operating instructions, a detailed description of the program, a Neliac source listing, an octal dump of the object tape, and a generalized flow chart indicating the sequence of events during the execution of the program.
