C# is the only language I've ever come across that support such a thing, and I only found that by accident because it would never occur to me to look for it. > My class is a debug helper class, that can write trace messages and so > on.

I would strongly recommend a singleton, or if you must use a static class you can either use the initialisation mechanism I described or, if the class has a single method as I'm guessing, have that method check the static variable to see if it's been set yet, and if not generate it before doing anything else. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
