That did it! Thanks! The tcp demo worked OK except for squaking about:

Warning: local constant txt1 in MyIPAddr.exw is not used
Warning: local constant txt2 in MyIPAddr.exw is not used

as in:

   txt1 = create(LText, "IP Address:", Win, 5, 5, 54, 20, 0),
   txt2 = create(LText, "Computer name:", Win, 5, 25, 77, 20, 0),

How do I get rid of the messages?

BTW, any ideas where I could get a simple CLI tcp demo, i.e. no Windows? This is
my first attempt at "winsock" programming, so I want to unclutter things as much
as possible. Thanks again.
