And I have to go back and retrieve 10+ year old learning.

I still get a chuckle remembering when we were 'learning' PING (gee, 
I already had Interop's Advanced TCP/IP class and Comer's vol II) and 
I figured the IP address of our terminal server and I gave it the 
PING of Death and we got a 15 minute class break while they tried to 
determine why the terminals all locked up.  Yes PING of Death was 
around LONG before M$ got slamed with it.

But how to use VI?  I have to pull out my book on that!  Thank you GEDIT.
