Abstract
A display system has a driver program for displaying alphanumeric characters and a driver program for displaying graphics. When a graphics window is opened, a program in the operating system establishes a control block containing a code that has been made unique within the user's program. For operations within a window, a function packet is passed to the appropriate driver. The operations are identified by the unique code and several independent windows can be created.
