Abstract

This paper describes a simple idea for extending the use of display segment files in computer display systems. The extension is to provide manual control of segment files in a display terminal as well as program control from a host computer. The use of display segments local to the display makes it possible to speed up the rate at which pictures are displayed when the communications line to the host computer is slow or when the host machine is time-shared and heavily loaded. The manual control of segments are terminal functions that work for any program including old programs that knew nothing about display segments.
