To model that with your approach would result in (a, (b, a?)*), which allows a string of b's with no intervening a's. Either way, you've changed the model. -- Regards, Marcus Carr email: mrc@a... ___________________________________________________________________ Allette Systems (Australia) www: http://www.allette.com.au ___________________________________________________________________ "Everything should be made as simple as possible, but not simpler." - Einstein
