Bear in mind that a==b returns an integer - zero if a!=b, nonzero (usually 1) if a==b. Thus a==b==c returns 1 is a==b and c is true, or a==b and c is false. If I've got the associativity right. a==b==c==0 does something similar. Probably inverts the entire above sentence - checking if something is zero is the same as logically inverting it... >nik >-- ABW -- "Simply drag your mother in law's cellphone number from the Address Book to the Laser Satellite icon, and the Targeting Wizard will locate her.
