No, because you can say:

print "$fh";

and find out exactly what is going on.

In the case with 

undef $fh;

$fh is true.

if ($fh) { print "HERE!!!\n"; }

print "$fh";

you get nada, right?

So... why the *$#$ is it getting into the loop?

There has to be a method to print out the *contents* of $fh, not just the 
values.
