advantages of RPN

[Don Shepherd]

I was cleaning up my hard disk drive today and came across this:

Enter versus Equals

I'm not a die-hard RPN fanatic who dismisses every non-RPN calculator as a piece of crap, but I do appreciate the beauty, simplicity, dependability, consistency, and programmability of RPN. To me, the HP-65 was the perfect machine regarding these characteristics. Not that it was faultless, but it did set the standard for those machines that followed it.

Alas, nothing manufactured today can match it.
