I started using Satellite Software's WordPerfect, CalcPerfect, and Draw in 1984 and visited their Orem, UT campus in 1985. Used and taugh others to use these products and used the linux version until 2000 when it died.
The author of WordPerfect, Bruce Bastien, just died <https://www.washingtonpost.com/obituaries/2024/07/05/bruce-bastian-dead-wordperfect/>. While the company made fatal business mistakes the quality of the software set a very high standard, far above Microsoft. Rich
