<p>PURPOSE:To simplify the structure of an application program by registering a table of font used as a mouse cursor. CONSTITUTION:When the font table is registered, a mouse control program stores its entry address and automatically assigns font numbers 8,000H, 8,001H,..., n to fonts defined in the font table in order from the first font. Font numbers 0 to 7FFFH are assigned to fonts in a ROM. When a font number is designated, the mouse control program discriminates a font in the ROM or a font of the application in accordance with the font number and refers to the corresponding font table to store the actual mouse font in the font storage area of the mouse control program and displays the mouse font on a screen. Hereafter, the font number of the new mouse font is designated to switch the mouse font. Thus, the structure of the application program is simplified.</p> |
