Hmm... I do not find something in these threads that might be related to this missing ENTER in the 12C Platinum version.

I should have written "This appears to be another one", that is, a new kind of issue.

Are you absolutely sure that the second ENTER can be omitted? This would be absolutely unusual for an RPN calculator: it's one of the RPN basics that ENTER disables stack lift so that here LastX overwrites X.

Yet the second ENTER is necessary on the HP-12C. I tried it on two units (CN04808261 and CNA 83816873). Really strange, I agree.

Best regards,
