Title:
DATA PROCESSOR
Document Type and Number:
Japanese Patent JPS61121131
Kind Code:
A
Abstract:
57 A data processing system is described that can execute a plurality of programs concurrently and has a display screen for displaying data associated with any one of the progams. Each progam maintains display screen data indicating the current status of the progam. The system maintains a REVIEW menu containing a list of the progams that have display screen data available. When a REVIEW key is pressed, the REVIEW menu is displayed. By pressing a further key, one of the listed progams can then be selected, and its display screen data is displayed on the screen. When the key is released, the information that was being displayed prior to operation of the REVIEW key is restored to the screen. A RESUME menu lists progams that are currently in a background mode, and can be called up by pressing a RESUME key, allowing one of those progams to be put into a foreground mode in which it has access to the screen. Another menu lists progams that are available for execution and can be called up by pressing a START key, allowing one to be selected for execution.
