Abstract
Disclosed is a method for causing an existing display and/or printing mode in a computer or the like to be preserved in sheltering areas located in memory upon commencement of an interrupt task. After completing such an interrupt task, the present invention causes use of the sheltered mode to be resumed. The present invention correctly preserves the originally existing display and/or printing mode until after completion of an externally generated interrupt task, thus effectively eliminating the undesirable process that is otherwise needed for reactivating the original mode.
