If I had a hash, I'd have to have a key and a value though. I'm just looking for one or the other. I suppose I could have key value pairs in the %SAN hash like so: Parker:san Bowen:san etc Then I'd probably stick all of the keys into an array. However, using a hash I wouldn't have to use a foreach loop or an unless, would I? That would make the Parker:san format and then dumping the keys into an array worth it. As for lowercasing or uppercasing all the incoming names, they are all in the same format, capital letter, lower case letters. I think what you were implying with using the hash is that if the incoming name matches one of the keys, it will overwrite that key. Since the names are in the same format, then there's no need to uppercase or lowercase them, right? __________________________________ Do you Yahoo!? Yahoo!
