Interesting.

Best guess I have is that it's a way to review all three statistics and still preserve some of the stack.

I was messing around with the statistical functions and noticed that SUM, MEAN and SDEV don't lift the stack. They just replace whatever was in X and Y. WMN, however, does lift the stack. That seemed curious to me. Since I don't have an actual HP 42s to compare this to, I checked the manual to see i...

Here are a few custom OFFIMGs I made for my on DM42 that I thought I would share in case someone shares my sense of humor. This first one is a dumb calculator joke. Something I whipped up in response to folks making the same joke whenever I post about my new calc. (It's upside down on purpose.) http...

This is probably as it should be, then, but in case it matters, the stack lifts for the first entries into MATA, MATB, and MATX as well.

Sorry to cause all this trouble. Unfortunately, I don't have 42S to compare it to. I had to depend on the kindness of you good strangers. :D So, on the original 42S, the EDIT function is the odd one out? That is EDITN, GOTO and all the arrows disable attack lift, but EDIT preserves it? Now I'm rathe...

Two for one! Score!

I'm not sure if this is the expected behavior or not, but when I open a matrix with EDIT or EDITN, if I try to key in a number before using the arrow menu keys, it pushes the old entry into the stack. If I use an arrow menu key first to move to a neighboring entry, then key in the number just replac...

Here's a program I threw together. It fills the alpha register with the equation from current curve-fitting model including the current approximate numerical values of B and M. I did my best to make sure that the whole thing fits on the screen when it's displayed, which might mean some swapping of d...

If you like RPN or RPL, you may be interested in some of the family of so called concatenative languages.

I missed this when I first responded to the thread. I'll have to check that out, too!

The www.racket.org link didn't work for me. Is this the same place? https://racket-lang.org/

I'll definitely check it out. Thanks!
