You could also decide to make "pos" take a return variable parameter for the position, as this would nearly always be neccessary. Its return value would then be a boolean, indicating whether the substring was found. You might provide an overloaded version without the return variable paramter for the rare case where you just want to check for _presence_, but are not interested in the _position_ itself. And maybe, an overloaded version also for compatibility that returns an ordinalized boolean result (for uses as shown above). -- -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
