I felt like King of the World writing stat programs with CalcStar.
I forget what it was called, but the spreadsheet I used with Lotus 1-2-3 became a massive semi-automated opus, but I couldn’t take it with me. So the next company I worked for, I redid the whole thing in Visual Basic for Applications. That was such a beauty, a visiting tech from Tokyo took a copy home and rewarded me later with a jar of nuts. LOL
Supercalc was a good one too. Lotus for DOS was always my favorite. DbaseIII was the other killer ap. It had a very handy SQL programming language that made desktop PC computers sing.
