From: lennie on 16 Jul 2010 14:53 Hi group! Apologies if this is trvial for you, but I try to construct a s/ / /g that will insert a - for every third digit in a number from right to left, ie: 123456 -> 123-456 1234567 -> 1-234-567 123 -> 123 (no - as first char) etc.. It might be possible to do this with a cpan library function, but I would like to have this done in a simple sentence. Regards Erling
