For one reason or another, XDE needs a routine that can search backwards for the first 0 (in other words, length( but searching backwards). I don't understand completely how length( itself works. Can anyone write one for me? TiA (no, the other one)!
And a length(XX)
r would be a nice feature for Axe, btw. Just an informal feature request
EDIT: Actually, never mind. I just realized I have Calcsys. Sorry to bug everyone.
EDIT2: If anyone wants, I can post the routine here.
