There are entire branches of mathematics / science devoted to recursive graph theory. Whole *BOOKS* written about it.

The most common solution was already posted. I'm sure that there are more in the textbooks. If it helps any, Common Lisp routinely dumps out cyclic data structures and reads them back in as text files. Of course, in Common Lisp, all the data structures are considered fair game for self-modification as source code, since source code and data have the same internal structure, so that's not exactly the norm in CS... :-) > I > have a few ideas but none very pretty.

You spiral into an infinite loop and slam the CPU and your computer turns into a door-stop until you kill that process. It's pretty unlikely that the current remaining bugs in SquirrelMail (which I use every day, btw) are caused by this, imho. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
