Abstract
A graphic display terminal is arranged to receive from a sending source drawing instructions containing the description of a display character. The terminal, under control independent from the sending source, interprets each received drawing instruction into a particular picture description bit pattern tailored to the characteristics of the terminal display device. The interpreted bits are then stored in a graphic repertory for subsequent retrievel under control of code received from the sending source. In this manner dynamically redefinable character sets may be created and used without regard to a particular terminal implementation.
