<p>PURPOSE:To return easily a window display to its original by providing a temporary picture memory 72, a temporary memory key and a re-display indicating key as a memory means. CONSTITUTION:When the temporary memory key 6-1 on a keyboard 6 is turned on, an indicated window number is stored in the memory 73 of a main memory 7, and the display area contents of the current window in a picture memory 71 is stored in the temporary picture memory 72 corresponding to the window number. When the re-display indicating key 6-2 is depressed, the number of the indicated window is read out, and the display data of the previously stored window is read out of the memory 72 and written in a corresponding window buffer 3. Thus, since the window display can be easily returned to its original, an operating time can be shortened.</p> |
