The site was new to me too, I found it by entering few key words in a search engine (no, the other one, 4-letter-named, starts by B-, ends on -ing).

Now -- vast subject drift, absolutely nothing to do with "Buy&Sell", but an attentive content manager might find the correct rubric to file it -- within that a. m. HP Handheld Conference 2014 gleanings I found

a comparison of four solutions of the same task on different machines with different programming languages. (There are only the slides without notes, no hint about the conclusion.) Mission: for numbers A and B (

input) compute (A-B)/B and (B-A)/A and show

output as %, positive value first or 1st on stack.

The shown solution for HP41 on page four looked a bit

too long (almost 'spaghetti') to me:

- Code: Select all
` 01▶LBL "PCH"`

02 X>Y?

03 X<>Y

04 %CH

05 X<>Y

06 LASTX

07 X<>Y

08 %CH

09 X<>Y

10 RDN

11 END

I suggest (two lines less but only one byte shorter):

- Code: Select all
` 01▶LBL "WTF"`

02 RCL Y

03 %CH

04 RDN

05 %CH

06 R^

07 X<0?

08 X<>Y

09 END

I assume that over time I am for sure not the first who found a shorter way to achieve the goal. So this append is just for the record: I also done it.
