04 LBL 00
05 RCL ST Y
06 RCL× ST Z
07 RCL+ ST Z
08 RCLx ST X
09 RCL× ST L
10 1/X
11 -
12 DSE ST Y
13 GTO 00
14 SQRT
15 END

Wonderful little program!
It uses the specific HP-42S stack capability, running it on my trusty 32S would require a few more steps. Of course the interest is in this 42S version.

Thank you Valentin, it's a pleasure to read you again.
