Abstract
In a word processor having a video screen capable of displaying only a portion, typically one-third, of a full page of text stored in a memory, a display advance system causes the screen to display the next one-third text section upon actuation of a control key. This is accomplished by (a) ascertaining from the location of a displayed cursor the identity of the next sequential text section and the initial address of the memory area storing that next section, and (b) generating the video display using text from that memory area, beginning at the next video frame.
