It's useful, but not as useful as it could be. It *looks* as if it could be used as a tokenizer (lexer) for e.g. a language compiler or interpreter, but if you try it, isn't good for that if any of your tokens are multi-character strings. Which is a pity, because if you have a simpler expression form that does have single-character tokens, it works fine for that. So that makes it look like an arbitrary limitation - why not extend it to operate on multi-character tokens? But I suspect the answer is because that's not really what it was designed for, and it only approaches this type of task. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
