No, I will not release my program with the alpha library, I'm only
testing it because I want to use DJGPP.

Yes I seek a lot, the data-bases are shared in a LAN, I can't pre-read
because any body can update it, I use lock files as semaphores.
Obviously the new algorithm works great for me :-)

Thanks DJ, Nate, Eli, SET, Robert, ... for DJGPP, it's a wonderful work.
