Spellbinder, from Lexisoft and later Ltec Inc, is a word processing
program originally created for CP/M and OASIS operating systems and
eventually competed with WordStar. It was designed as a work-alike of
the NBI Word Processing system and featured spell checking, grammar
checking, footnotes, two-column print, proportional printing, and
macro programming language. It was bundled with machines from Eagle
Computers, Hewlett-Packard, and Xerox.
