<p>PURPOSE:To provide a function the same as window display of bit map system by providing a means which eliminates data of plural byte systems when they are set spreading over a boundary from a display object. CONSTITUTION:A CPU 1 executes display processing control according to a window system 21 stored in main memory 2 and a display processing program 22 included in the window system. The CPU checks the boundary of view when codes of plural byte systems accumulated in text memory 3 for display are displayed on a view port, and omits the data when they are set spreading over the boundary. By employing such processing function, it is possible to eliminate inconvenience to destroy a screen due to character change by the spread of the codes over the boundary of the window, which provides the function the same as the window display of bit map system.</p> |
