Abstract
A technique for displaying a representation of a full page on less than an entire CRT screen in a word processing system. The full page representation uses character indicators to enable the word processing system user to appreciate format and spatial relationships with regard to page boundaries. Within the miniature page the interlinear spacing chosen by the operator for the hard copy output is properly represented. Integral line spacing is achieved by displaying blank lines as appropriate. Non-integral line spacing such as half-line spacing is achieved advantageously through manipulating the particular character construct utilized. A character representation matrix is usually blank at the top and blank or non-blank in the bottom half. Reversing top and bottom halves removes one half-line of interlinear spacing.
