Now that sounds like a nice compromise in a few places where exceptions have been introduced, but I still think this is still a little chicken and egg. If it is going to 'fail' then the reason for the failure is more important than simply producing no answer. Especially if it is going to fail in different inputs to other methods. Again forcing an exception only solution sidesteps that debate! -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
