Aha, things begin to fall in place here! I never thought of the space in format. I relly didn't think it made a diffefence using "%6d %5d %5d" instead of "%6d%5d%5d".
Thanx a lot, I think I got it now!!! (The "non-ascii" from my name is the Scandinavian "a" with a circle on top of it. If you set your keyboard to Norwegian, you will find it to the right of the "p" on your keyboard. The substitute for it is actually "aa" so my name can be written "Kaare".) K.
