I leaped on this thinking it hadn't picked the longest match and was therefore wrong. You're saying that since it consistently searches backwards using the *start* of the string, not the end, it is the longest match from that point, and it won't be able to find a longer until the start has moved back. I already realised the change was incompatible with the way % worked, so I'll back it out and instead think of something to upgrade the documentation. I'm just tackling this in the user guide, but tackling it at 11 pm after working all day probably wasn't ideal. -- Peter Stephenson Software Engineer CSR Ltd., Unit 300, Science Park, Milton Road, Cambridge, CB4 0XL, UK Tel: +44 (0)1223 392070 ********************************************************************** The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
