Thanks for your response, Amado.  Dmitry Kazakov pointed out the same
solution in a different message.  (Although from your post timestamps,
it appears that you suggested it first. :)  But I question the

parameter that makes what I'm trying to do an error for one, but not
the other.

Thanks again,
Tad
