that's wrong btw. You've just assigned 'gp to the result of try, which in
turn can be error object. What about:
if not error? try [gp: open/direct/binary probe join tcp:// [ip ":" port]]
[insert gp "GNUTELLA CONNECT/0.4^/^/"]
note - join knows how to work with datatypes - provide first argument as
url! and it will convert rest for you ... see my code ...
