The problem with using hashes is that a typo means the argument doesn't get passed. One of the things `use strict;` does is catch spelling mistakes. I find that many of my arguments end up as globals. That, of course, means my subroutines are not re-enterable (that is, without the clever use of `local`), but I tend to use loops rather than recursion. -- __END__ Just my 0.00000002 million dollars worth, --- Shawn "For the things we have to learn before we can do them, we learn by doing them."
