Doesn't work on my 7-STABLE system (20080811), awk stops:

awk: syntax error at source line 78 source file konvertieren.awk
 context is
                sub(nr, "[a-z]", " >>>  &" <<< );
awk: illegal statement at source line 79 source file konvertieren.awk

But I'll keep your suggestion in the program source and test
it on 8 as soon as my "new" home system is ready to use. At
least, the & variant looks much better.
