HP35s RPN Series # 3 [ENTER]

[Sanjeev Visvanatha]

If you look at the older manuals, there was an entire chapter devoted to stack mechanics and the Enter key. Something so complex requires a simple designation on the keypad, IMO. The user has to read the manual, experiment, and gain confidence in what the machine is doing. It doesn't take long for a technically minded person to master it.

You had mentioned the "=" key earlier. Well, "=" is also in the same boat by your logic. It doesn't equal anything unless the user understands OOP and the use of parenthesis.
