You could be right.  We only have a handful of join logicals, of which I
think I have created zero.  And we don't have many join OPNQRYFs, of which I
have probably created zero also.  (Nor do I use embedded SQL <gag>, I roll
my own join logic in the program.)  So I've never had occasion to actually
see if that would work or not.  And since it's something I don't really care
about, I'm not going to bother and see if I can persuade the query engine.
(But if you want to borrow my hammer ... <G>)
