Thanks for the pointer, blakem. Did the trick, and I'm on my way.

There's one ref in the pointer you gave me that addresses a 'Pure' way to do it using seek. It seems that many the replies addressed all the ways to find the tail end of a file in an efficient way, but vnpandey gave the most helpful answer in Re: Is there a way to read a file backwards?

That was great help.
