Thank you very much again for the sample code. I am convinced that it will be very useful to many other people, too.

I am not working just for fun, but I am my own boss, so I guess it will not be too difficult to convince the boss that making patches is worth the time and effort (I occasionally have done such things in the past for other projects, too). I'll look into the POD format and the patch submitting process ...

Thanks again,
