Thanks for your answers Philippe, Yet I stil dont understand what I am supposed to do exactly for the first point. I tried out what you proposed but I didn't get what I expected. I enclosed three files with this mail: could you show me what you would do exactly to make the script "Test.C" work? thanks a lot, Martijn A 11:29 09/02/2004 -0600, Philippe Canal a écrit : > > 1.
