Abstract: A data processing system which gives an application (50) running on the operating system (10) direct access to the output display (42). The system is operable in two modes. In the first mode, if the application displays text to the output display, the output data must go through every layer of the processing system before it reaches the output display. In the second mode, the application can output data directly to the output display without going through the many layers of the processing system. In this second mode, a buffer (15) is defined by the application. Input data from the input devices are stored in this buffer. The application accesses the buffer for direct output to the display.
