Sqlplus -S interrupt !!!!

[Gianni]

Im trying to use perl to launch some sql and it works fine

$command = "sqlplus -S " . $usr . "/" . $pwrd . " \@mccci060.sql";
print "$command";
$status = system ($command);
print "status" . $status;


the problem is that if I give the above line the wrong user and
password Im not able to intercept the error , perl just stops and cant
write logs.
Consider that I don't see the result of $status as the program stops
just before it !
Thanks
Gianni
