This is probably because I still don't understand objects, as I still just consider them as arrays with a few more complex elements. I STILL work on the basis that is I pass by reference, I can make modifications to the data while if I don't I get a copy and have to pass the copy back if I need the original changed. This used to be all very simple, so when did it stop working? This may explain why I get into trouble with stuff that has been working for years but after 'modernising' starts throwing problems :( -- 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
