trying to use DBI with mysql and a stored proc
the proc has 14 input and 3 output params
I can get it to actually do the work but can't get the return codes
any ideas?

my $sql = "call PROC_MEMB(?,?,?,?,?,?,?,?,?,?,?,?,?,?,\@code,\@key ,\@map)";
$RegUser = $DBRegUser->prepare($sql);
$RegUser->bind_param(1,$action);
$RegUser->bind_param(2,$user_uid);
$RegUser->bind_param(3,$locale);
$RegUser->bind_param(4,$username);
$RegUser->bind_param(5,$pass);
$RegUser->bind_param(6,$dob);
$RegUser->bind_param(7,$gender);
$RegUser->bind_param(8,$title);
$RegUser->bind_param(9,$letters);
$RegUser->bind_param(10,$firstname);
$RegUser->bind_param(11,$initials);
$RegUser->bind_param(12,$lastname);
$RegUser->bind_param(13,$knownas);
$RegUser->bind_param(14,$suser);
$RegUser->execute();
$RegUser->bind_columns(undef, \$code, \$key, \$map);
$RegUser->fetch();
print "Code::$code, Key::$key, Map::$map\r";

I get nothing back - I know they are working correctly as the output params write to a db log table correctly
