Re: Pcalc

What makes Pcalc superior to either of the HP48 scientific calculator apps? Can you create equations and save them for use in the Solve mode, like converting blood glucose values to HgA1c values.

RPN is awesome. I liked the HP calculators so much that I wrote my own HP emulator application on a Mac Plus. It had all the scientific functions, and the banking/finance functions, and the programmer functions.  I sold a few shareware copies of QuikCalc, but mostly it was for my own benefit. :-) (I did get paid for a MacTutor article I wrote about the Help system I developed.) One fun thing that I never saw anyone else do back then (1986 or so) was make the buttons appear to depress on the B&W screen by redrawing them with the shadow reversed from bottom-right to top-left when they were clicked.

Retirement is just a couple of years away and I'd like to start programming Macs/iPhones just for fun then. Renewing this program will be one of my projects for sure.

I used an HP 11c calculator from my sophomore year in high school calculus class for about 15 years. I haven't used it for about 20 years though.

I now use Pcalc on the extremely rare occasions I need to use a calculator (and I own two HP clone iOS apps).
