I did this and I'm now getting the following error:
IO::Socket::INET: Unknown error at 415b.pl line 2
Can't connect to daytime port at localhost at 415b.pl line 2.
That's what I was getting last night (I changed various things and compiled but got
various errors each time). The problem, to me, lies with the IO::Socket::INET
statement (correct?). Any ideas? Thanks!

you want commas to separate list elements, not semicolons.
use IO::Socket;
$remote = IO::Socket::INET->new(
Proto => "tcp",
PeerAddr => "localhost",
PeerPort => "daytime(13)"
)
