Abstract
Abstract There is described a technique for use in a word processing system for displaying a representation of the full page of text (152) on less than an entire cathod ray tube screen where the full page representation is proportional to the hard copy output which eventually results. Dynamic mode switching is employed which enables the output on a given line of the display of both full size characters (156) and miniature character (158) representations. Dynamic mode switching also provides control of the placement of the miniature page representation on the CRT screen.
