Hi Dore,
This is true. I would be considered a newbie when it comes to NULL because I have not ever used it for anything probably because it is not anything (unknown). I will check it out though. I see your point.
Maybe they should invent a command called VOID (as in REVERT), then you could use NULL and VOID. LOL!
Thanks for the idea. I will keep it for future reference.
