Not sure exactly if this program is a spell corrector, a dictionnary or something similar. Following some files included, it seems to integrate with others odd word processors such as the following:

Ability Plus, Displaywrite IV, EasyWriter II or here and here, Enable or here, Microsoft Word, Microsoft Word 4.0, MindReader or here, Nota Bene, Ready!, Spellbinder or here and here, Volkswriter 3, WordStar 3.0, WordStar 2000 and XyWrite III.

Doesn’t seems to be made for WordPerfect…
