I have just learned, to my astonishment, that half the lawyers in New York create their documents in WordPerfect. That is not a typo.
I may as well admit here that I still have a copy of WP 5.1 for DOS; the executable (a mere 213k) is dated 6 November 1989. Apparently the last time I used it for anything was in 1999; I have a ZIP file of correspondence that was created in 1991.
Alas, I gave away my copy of WordStar, which I acquired along with a brace of Osborne 1s back in the Jurassic period.
