Abstract: A data display system in which input-output display devices are connected to a central processor and users select application programs that are run on the central processor and including in the control system of the central processor; a display manager control system and a windowing control mechanism which allows a plurality of tasks to be performed concurrently and the results displayed in areas of a display screen, characterised in that the windowing control mechanism includes, a task manager control program which runs as an application in the display manager control system and includes, means to interact, via the display manager, with the operator to allow applications to be initiated, means to create tasks to control the processing of the application in such a way that the applications can be suspended or resumed according to whether operator is available for them, means to identify to the display manager a coordination controller that the display manager can call to allow the task manager to suspend and resume applications, said display manager including, means to combine data from each application and build a display representation that shows many windows into the various applications onto a single screen and, means to call the coordination controller identified by the task management application so that the task manager can suspend applications that are waiting for input and resume those applications which have input available.

Abstract: A MULTIPLE WINDOW DISPLAY SYSTEM A multiple window display system includes a display device and a screen ownership area pointing to the identity of the window which is to contribute the data for each display area of the display device, characterised in that an ordered list is maintained of the active windows in the priority order thereof, means being provided to regenerate the screen ownership area from the list, on each change made to the list, in terms of list position per device display area, by overwriting, progressing through the list in order of increasingly significant priority order, the list indicating, in each position thereof, the identity of the window having the respective priority. The list contains the addresses of the windows in storage and the type thereof. The screen ownership area is reset to the lowest potential priority list position value and is overwritten. UK9-86-015
