Thanks, I've just come across (?:pat) this morning when I woke up to have another go at the problem and thought I'd finish the chapter of Cozens book first. I'm also taking a look at the perldoc and tutorials (actually after only a few moments of reading I realised where I was going wrong and why $2 $3 and $4 don't exist!). Because perl matches as soon as it can, as much as it can and ends as soon as it can it was never going to find anything beyond 'Three' with the match I was making, (a very blunt and undetailed statment rewording your earlier post). However overall I think the exercise has been a sucess, I made the program to check my understanding of RegEx and it has lead to the discovery of new material to help me with this and future problems. I'll look at resolving this problem again once I have covered the material. Thank you for your patience, Regards, Keystone.
