WINDOW DISPLAY SYSTEM AND METHOD

摘要

A windowing system is provided as an interface between application programs and non-programmable terminal drivers. The system presents logical windows to the applications program, each of which are represented internally by at least two separate parts. The first part includes the border and non-scrollable text for a logical window, while the second part includes scrollable text for the window. Through calls to the display driver 9 the windowing system manipulates these separate parts so that they are displayed on the screen as a single window.
