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

In "Operation [ENTER] Number", the ENTER is optional.

... and that's correct for every HP RPN calculator.

Hang on - I see the confusion. That's not what's at issue; what I'm writing about is

"Number [ENTER] Operation"

in response to the original quote: "Pressing ENTER is optional after entering a number, if the next key pressed is an operation." This reinforces my point that the original places the emphasis on the wrong concept.

I might press "operation ENTER ENTER Number", if I want to duplicate X before entering another number, but I'd never press "Operation ENTER Number" or "Number ENTER Operation".
