Thanks a lot, Morton. Yes, I've modified my approach. I just had to 
expand my mind to really consider how to contain each discrete thing 
that I want in these huge text files I'm getting. Once I've got them all 
in an array, I see now that I can do stuff to each entry in the array. 
Exactly what I need. Your suggestion helped. Thanks again.
