I tried again (after failing half-a-dozen times) and IT WORKS.
The only thing that was different this time was - I noticed
that IBAccess defaults to Dialect 1, and changed that to
Dialect 3, then it worked. But later I tried again and forgot
to change to Dialect 3, and it still works.
I need to explore this further.

Next problem was with the table name - I created it as Guest.
kinterbasdb (or Firebird) complained it could not find table GUEST.
But when I recreated the table as GUEST2 (and adjusted my
SELECT statement) all is OK.

Anyhow, I now have a minimal PythonCard program
(in Windows 2000 Pro) accessing a FireBird database.
Time to relax and celebrate before the next problem.

Thanks to all for suggestions.
