Abstract
In a word processing system having a keyboard display for data entry and modification, and a printer with a choice of pitch, the technique is presented for displaying on less than the entire CRT screen a representation of a full page of text being processed. The full page representation is in fact visually proportional to the yet unproduced printed output. The full page representation is made possible by using a 2.times.4 character representation structure to represent an 8.times.16 normal character. Proportionality within the represented data is achieved by displaying particular character representations more than once. The interval between multiply displayed representations is a function of the output pitch with which proportionality is desired and the size of a dot on the CRT screen.
