Thank you very much Hans.  This is just what I needed.  I'm happy 
to read the documentation now that I know where it's at.  
Boy !  I sure am glad you started me off on the right foot with the 
suggestion of adding the statement "my ($ip, $user, $pass);"
I would have never guessed that from the FAQ.  Since I ran the 
script once with the "use strict;" statement and then commented it 
out because it generated so many errors I'm guessing even though 
the program ended I would have to sign off the session for it to not 
"use strict;" while running.  Pretty strange it persists after the 
program ended. 

Thanks again,

Gary Kuznitz
