Need and need, it is good practice. So good that some compilers will raise a warning if you fail to do it. The point of void here is twofold, to let the compiler check that the return statement doesn't try to return anything and to let the compiler check that the caller isn't expecting a return value. Other types have similar checks. _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
