<p>PURPOSE:To revise a size after a size revisable state is confirmed on a display screen when a mode revising a window size is instructed by temporarily displaying a specific window peripheral frame and erasing it after the size is revised to optional one. CONSTITUTION:By a micro processor unit 11, when the revision instruction of a window is recognized, the specific window peripheral frame showing that the window size is revisable is displayed temporarily. Then, the display data of a window frame display area of a window periphery in a main display area in a RAM 14 is retreated to a non-display area in the RAM 14 temporarily, and the frame data are written in the area. Thus, a window screen added with the specific window frame is displayed on a CRT display 13.
