ABSTRACT:
A multi-window display control system, which is constructed so that a plurality of terminals having a multi-window display are connected through a terminal controller with a processor having a high priority and a processor having a low priority. One of the terminals is assigned as a common terminal displaying messages coming from either of the processors. The terminal controller is provided with a save buffer. The frequency of use of each of the virtual screen buffers of the common terminal is stored. When a message coming from the processor having a high priority is received, the virtual screen buffer, whose frequency of use is the lowest, is selected among the virtual screen buffers of the common terminal. The message is stored in the selected virtual screen buffer after having saved the content of the selected virtual screen buffer in the save buffer.
