  OK, thanks, it should be easy for me to generate a .df3 with no 0 value.
Concerning the 3.7 beta 28, I tried to compile it on my lab's computer, but
there were several errors which I could not correct as I do not know C... But
it is no big deal actually, what I have for the moment is really satisfactory.

  Thanks a lot,
