I have made a tree function as well, which of course uses a stack too. Btw, this tree function is actually made of two functions, one called tree-builder and one called tree-parser. The tree function the looks like this: set 'Tree func ["Print directory tree" dir [file! unset!] "Directory to list" ] [ any [value? 'dir dir: %.] tree-init tree-parser tree-builder dir ()] tree-init initialises the rules to use when parsing the tree. This way you can easily make several function with various effects, like cloning a directory structure, running all scripts matching .r etc... Eventually tree-builder will be able to take patterns too, like recurse does, but without paths like */* becuase paths make no sense for tree.

It would be good enough just being able to translate "?*" to some 'parse rule. Marcus ------------------------------------ If you find that life spits on you calm down and pretend it's raining
