Please post the code. Given the above, the only 'help' we can provide is to say "You can't use an undefined value as a reference". :^)	[reply]

Greetings, ...and while you follow virtualsue's suggestion, take 5 minutes to pepper your code with print statements and error checking clauses, such as: `#turning this... my $sock=Io::Socket->new(...); #into this my $sock=Io::Socket->new(...) or die('foo!');` [download] With a 99% chance, you are forgetting a check like the one above. Cheers, alf You can't have everything: where would you put it?	[reply] [d/l]
