I've seen num? and chop but think I need something in the middle to turn a character to a number.
Having said that I seem to have got close by accident...i.e. I was going to try and bend this...but it found a single integer as it was :) : (pick '((Ch) (and (= Ch (uppc Ch)) Ch)) (chop 'ab33Cd)) -> "3" I'd like this to detect 33 but see that chop precludes this. Any help much appreciated.
