>Okay now I'm really confused. I took your code and made some slight modifications to it (see below) and I got the following results:

Why does that confuse you? You check for a prop, it doesn't exist (.F.) you call a method which adds teh prop, then it does exist.

Remember you are usingteh same object DIRECTLY in all cases! That point of my code was to realize that by passing the object pointer, you are only passing the object pointer, wether by Value or Reference, it doesn't affect the object but just what its reference points too. You could change oObj to a .Null. or 6 if you want.
