Can we have RPN back?

[Craig Thomas]

My HP-48SX, my HP-48S,my HP48G, my other HP48G my HP32Sii, my HP15CLE, and my other HP15CLE all have keys that mean things and serve as an indicator as to which numbers are about to be used for calculation. This was all based on the really simple context of knowing that the first two registers in the stack were thought of as X and Y. Some have a four place stack and some have a limitless stack.

On these older models some have one function key that refers to X and y, and some have two.

To those with my experience, on the Prime, we just have to remember that the two 2-argument keys are labeled backwards and all will be well.

Which is a really good reason to not use it as a replacement for your favorite old engineering calculator since these keys don't work in the expected way...expected based on 30 years of use of "old" Hp's.

I read what's on the keys, and enter data accordingly after automatically assigning X and Y to the first two registers...meaning I'll make mistakes trusting the Prime.

Which is why I asked for a "legacy" RPN mode that would reverse the action of the two keys on the Prime for legacy RPN only.

What I would like to find is that I could do this myself, so that if I enter the RPN mode the Prime offers now, it would automatically reverse the action of the keys. I don't see how to do it. The User Keyboard seems possible, but I'd prefer to redo the keys only in RPN mode.

As for the gentleman who calls all this silly, I disagree. It's a small issue, but it's not silly. It's a 30 year habit for some of us.
