Re: what's the error?

$! is not guaranteed to be cleared if there was no error. This means you
probably don't have a "Bad file descriptor" error, it's just the last value
of $! (or 'errno').

That's confused.
Since there is not such an error, I was thinking $! or $@ shouldn't 
include an error value.

Thanks anyway.

Ken.
