HP-12C gets 'Entry-RPN' or Error in the QSG?

2 ENTER 3 ENTER +

With an HP-12C you get 5 and 6 while the result is 5 in both cases when using an HP-48 (or 20B/30B).

Where did I say so? Both results are 5.

Kind regards

Oops! Sorry; that was a typo. I meant to quote what you wrote, as seen above: "2 ENTER 3 ENTER +" does indeed yield difference results in the 12C (6) and 20b/30b (5).

My point remains the same: the underlined ENTER above is pressed after a number, not after an operation. Pressing ENTER after an operation is optional on all HP RPN calculators. Since this is certainly correct, and since HP's statement can be understood that way, it seems clear to me that that's what they intended it to mean. They clearly did not write it clearly.
