Abstract: The disclosure relates to an improvement to an information processing system for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing affects only the format of information. The improvement provides the combination of means for initiating a data processing session in said system, means for switching to a text processing session before the completion of the data processing session, means for storing the status of the non-completed data processing session during the text processing session, and means for switching back from the text processing session to the non-completed data processing session.

Abstract: A computer system having a display adapter, a refresh buffer and an interactive display terminal with a screen display on which is formed a plurality of at least partially overlapping windows, a depth buffer is added to the display adapter for providing clipping assistance to the software-based window manager in the CPU. The window manager is programmed to monitor the current depth position of each of the plurality of windows. In response to an input request for a rearrangement of the windows, the window manager assigns a new depth value to the subject matter associated with each affected window and requests that each application retransmit at least the affected subject matter. The depth buffer includes an array which stores the depth values of the subject matter associated with each of the windows being currently displayed on the screen. In response to the rearrangement request, depth buffer receives the new depth values for the subject matter associated with each affected window from the window manager and compares the current depth values. If the comparator determines that the new subject matter has a depth value associated with the same window or a window closer to the viewer, the depth buffer notifies the refresh buffer to store the newly transmitted subject matter from each of the applications being run on the CPU. In an alternative embodiment, two buffers are used to store the depth information associated with the subject matter in a window, i.e. a W-buffer to store the depth of each window relative to a reference point and a Z-buffer to store the depth of the subject matter within a window.
