ScreenExtender is a series of add-on software enhancements for
popular word processors such as WordStar and WordPerfect.
ScreenExtender increases the amount of text that is visible on the
screen at one time. It does this by enabling smaller text characters
at higher resolutions. Such text modes, up to 160 columns and 58
rows, are commonly possible with VGA adapters, but ScreenExtender can
even extract extra screen real-estate on CGA, EGA, and MGA/Hercules
graphics cards.
