OOOOOHHHHHHHH!!!!!   I get it!!!   That is SO simple!  I get it now.  
Thank you SO much.   My head and the wall here thank you too.

I knew I could have daisy chained two greps together like you did, but I 
try to limit the number of processes that I make the system run.  My 
efforts to stop doing  'cat filename | grep search_criteria'   seem like 
the best way to keep the Dept. of Redundancy Department off my derierre.


Thanks, Wayne.   PHEW.
