On that subject, for text programming, the use of recursion is almost always the sign of an inexperienced or poor programmer. The worst offender in this is the Java REGEX package, which is almost useless for large document text processing, because of stack growth in some pathological cases with some harmless-looking regular expressions. Tree-walking and small-stack problems are a different kettle of fish, of course. Or when using languages with the tail-recursion optimization, of course. Cheers Rick
