The more I think about it, the more I like this approach. Most token should be matched in ratchet mode, and I think minimal matching is perhaps a form of cheating: "Look for the nearest end of this without me actually bothering to parse the middle." And certainly any reasonable grammer is going to be checking that a keyword is properly terminated by a word boundary anyway. Larry
