Thanks

But it does not explain what I was observing. Only one of the methods was changing the ByRef arguments to a ByVal behaivor. I am doing this because several of the string arguments get altered, and I need the results upon return from the method(s). This may not good programming habit, but it was result after refractoring the parent method.

I resolved the problem (for now) by moving the child methods code back to the parent.
