use Finance::Currency::Convert::Yahoo; $Finance::Currency::Convert::Yahoo::CHAT = 1; $_ = Finance::Currency::Convert::Yahoo::convert(1,'USD','GBP'); print defined($_)? "Is $_\n" : "Error."; exit; # See the currencies in a dirty way: use Finance::Currency::Convert::Yahoo; use Data::Dumper; warn %Finance::Currency::Convert::Yahoo::currencies; exit;

undef in response, with errors going to STDERR, and notes displayed if the modules global
$CHAT is defined.
$value = &convert( $amount_to_convert, $from, $to);

%currencies hash. (For the date this was last checked,
Please see the enclosed file CHANGES.
