>SELECT() and ALIAS() are both documented as to what happens when nothing is passed. TAG() and DESCENDING() are not. If I read between the lines, I think you are saying that I'm ok assuming the problem is just one of missing documentation. I think that this is the case.

TagNo(), TagCount() were not documented at all in some of previous versions, and still worked. The behavior of this class functions remained unchanged accross five versions of Fox. At least, sounds assuring.
