Thanks. I didn't know it was a bitwise operator ... Was trying to find the
right way to go about it in the manual, but when you don't know what it's
called in English, it's a bit of a problem ... and since the Danish version
of the manual isn't up to date, I don't really use it...
But thanks, looks like what I want ... thank you...
