This is the cause of the confusion. The differences are quite different. RPN is a mathematical notation, RPL describes a programming language.

You can compare RPN to Algebraic-notation or RPL with Keystroke-programming but not RPN wirh RPL...

Yes Peet, you're right and it's always good to emphasize the difference between RPN as a mathematical notation and RPL as an object-oriented programming language. However, in the above discussion of the difference between RPN and RPL, RPN is just shorthand, as is common in the forum, to refer to HP's classic keystroke programmable models vs later RPL models. The alternative is to write out each time something like "keystroke programmable." So in the spirit of RPN (to save keystrokes :), I'll probably still say RPN to refer to keystroke programmable models when the context is clear.
