HP35s RPN Series # 3 [ENTER]

[Don Shepherd]

Mark, that's quite a writeup on the ENTER key!

What seems to be lost in all of this, however, is the basic purpose of the ENTER key on an RPN calculator: it separates the two numbers in any arithmetic operation. If you don't have an equal key to deliver an answer, you need an alternative. All a casual (or new) RPN user needs to remember to operate his/her calculator successfully is that you separate your two numbers with the ENTER key, and press the desired operation key last.

Of course, RPN calculator programmers realize what the ENTER key does, but your average Joe is not a programmer and doesn't care about all that. There is just something "elegant" (shall I say) about separating your two numbers with the ENTER key and then specifying what you want to do with them.
