David, that was also my first guess, so i took a look at the .dat-file
(opened it in an editor) and it seems to me as if the last line was
indeed empty (cursor can be placed into the last line which is empty).
then I did the conditioning, but it says there is no "empty" lines
(count = 0).
however, i think i made it work now - at least that's what my tired
brain thinks.
I'll take a closer look into this after the weekend.
bye everybody
