I saw this need coming but wanted to avoid it. I think what I'll do is
place a tag somewhere USEODBC=? and use this to decide which SQL to use,
ODBC or Jet. Our unfortunate situation is that the guy developing the
Access end is unable to run PG anywhere so his datasource has to be a
.mdb file (any suggestions?).

What's the time table? Anyone expecting to work on this any time
soon? I'd help but I don't know C very well and I have no development
tools in Win95. :( -or is that :)

Thanks.. That's what I wanted to know.. I've been able to find things
before in MS's archives even when I didn't know what I was looking for.. I
just wanted to know if what I'm looking for exists before looking :)
Thanks for the quick reply
