<p>A graphic display terminal (Fig. 1) is arranged to receive drawing instructions containing the description of a display character. The terminal, under control independent of the source, translates each received drawing instruction into a picture description bit pattern conforming to the characteristics of the terminal display device (7). The interpreted bits are then stored in a graphic repertory (10) for subsequent retrieval under control of code received from the source. In this manner dynamically redefinable character sets may be created and used without regard to a particular terminal implementation.</p> |
