In a system in which a system continues processing as the main system, the data up to that point is always saved to the auxiliary storage device at the end of the control process of the main computer, and after system switching, the saved data is used. A master/slave system switching device for a dual system, characterized in that a means for ensuring continuity of processing is provided.
