Thanks Ed,

I normally do check for .NULL. when using type() but vartype() takes a lNullDataType argument that will return 'X' if it is .NULL.

I am trying to figure out why it is doesn't behave like it is documented to. It says that vartype() will return 'U' if a var doesn't exist. But so far, I am getting an error.

I would hate to get bit later on, by using a function and it doesn't work, ya know.
