Nils,
Thanks for the reply. You made me look more carefully to the first line 
(I used hexedit to look at the key-codes) and silly me had not detected 
  the spaces in the text. Now it works perfect.
@Normand,
Thanks for the suggestion and the complete realization for my problem. 
However, I'm as Johnny Rosenberg, I have never mastered AWK and I don't 
need that very much. When I have more complex scripts to make I use perl 
instead of bash. There I know how to manipulate strings.
Everybody, thanks for the help anyway,
Joep
