For me at least, that was sufficiently implied by the original email. That's why I explicitly referred to the K... P... ... heuristic. The last part (the three dots alone) was meant to match three-letter IDs. > I think we > use 4 character ICAO codes for everything outside the USA. Mostly but not entirely true.

It is easy to handle any such countries. Anybody who knows of any is encouraged to report them. There can't be very many. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
