>I speeded up you code:

Actually, it's Garrett's, but I was cheating from him. :)

I was able to speed up the results to .05 seconds by switching from using strtofile to using FREAD, etc. The other problem with the algorithm is that it, well, doesn't work. It misses some entries.

So, if nothing else the VB's guys beat us to a solution that is correct.
