I had thought it was just some sort of cryptic progress meter. :-)

LOL - I know what you mean.

I'm still going over your original code to see how you did what you did -- trying to learn some perl :-)

I'll give the new code a try. I also see that the minimum length in your code doesn't have to be a power of 2. This should allow me to analyze a limit boundary that appears to be present in my data. Grandfather's code allowed me to come up with what I feel is a pretty good estimate for the value of the limit, but this should allow a closer examination of the limit.
