Thanks, I'm trying to get the actual numbers now.  In your opinion is it 
doable to add incremental update functionality without being too 
intrusive on the existing code base? (I'm guessing modification to zonec 
would be the only changes).  Can new records be simply appended to the 
DB or would insertion have to be done?  I'm still kind of fuzzy on the 
DB file setup.
