I kept discovering features that helped. Very early versions had a Leap year determination routine. At one point I wondered if wp34s had a leap year function, that saved a ton of steps. Then discovered the Date arithmetic, which eliminates the need for leap year determination altogether as wp34s knows that the day before 01 March is 29 February in leap years. (I knew it had Prime? all along, I never tried to build a prime checking routine.)

Never thought to check if END works like RTN, just figured it is the separator for alpha labelled programs. Of course, the manual clearly states “Works like RTN in all other aspects.” So I will accept that reduction, although then it seems like we should count the final END statement, so maybe no reduction. I think the label is needed to make it easy on the judges to run multiple test cases.

Thanks again for your comments.
