ABSTRACT:
A personal computer having an interactive all points addressable display terminal (44) and a cursor positioning device (52) and provided with apparatus for facilitating the generation of a graphics display using cursor characters selected from a table of cursor characters is capable of clearly demarking the currently selected cursor character from characters previously fixed at various points on the all points addressable display. This is accomplished by exclusive ORing the selected cursor character data with the corresponding data in the all points addressable display at the current position of the selected cursor character.
