In about 1985 my boss needed a program that would compute an chart both Least Squares and Demings Regressions. The platform given to me to work on was Lotus Symphony. CompuServe had a forum for coding and I was able to write the whole thing in @Functions. The app survived my RIF and was still in use a few years later. Fast forward into the mid 90’s and I recreated the same app in Lotus 123 for windows using the same language but had the advantage of regression being a built in function. I think that time around I was using ListServs for help. Good times. Good. Times.
