Hi Ben, hi Gabriel,
thank you for that quick aid.

Gabriel, in fact I new already the things used in your and Jeromes  
macros, but did not combine the things as necessary.

Ben, this quick java extension is working very well. I think I have to  
extend my java reading capabilities to writing! Although, that is the  
wrong way around: In Waldorschools the students learn first to write  
and than to read (with surprising efficiency)!

Best regards and seasonal greetings
Karsten
