ABSTRACT:
In a data processing system, a self-diagnosing system selectively initiates the operation of subprocessing units in the data processing system in a predetermined sequence to determine whether the subprocessing units are operating correctly. A control store stores a plurality of sequences of control data which are selectively accessed to control the operation of the subprocessing units to perform self-diagnosing error tests. A display unit displays an indication of which of the sequences of control data is currently controlling the operation of the subprocessing units in order to aid error diagnosis should an error be discovered during the operation of the self-diagnosing system.
