Mike --

One more minor point in this issue. Your suggestion is not identical in effect to the suggestion I prefer:

type("alen(loForm.arrProperty)") <> "U"

Your suggestion fails if the property / memory variable does not exist.

I mention this only because I always try to be very careful when replacing code with "better" code to make sure that there are not some edge conditions not accounted for.
