Cheers David - it was the one that Wayne points to that I was after but
I agree regexp's are incredibly useful, if you can only remember the

Yes, and certainly! I'm still an astronomer, but I'm also working in a
collaboration looking at medical imaging too. I'm finding it very odd
dealing with images where the subject is close enough to ask to move
round a bit, you just don't get that co-operation from galaxies...

I think you must be talking about that wonderful (nee miraculous)
function Stregex. Combined with StrSplit and StrJoin, fabulous
things can be done in a single line!

P.S. Have you moved back to Edinburgh? Is your apartment
big enough for a visitor? :-)
