As you can see, it is very similar, but since we get the whole file into the

of looping and getting one line at a time until we get to the end of the

Hello Derek,
When using strict, the error message should point you to the line where the

case, I bet it's this one:

There is no declaration of the $line variable. Try declaring it f

An empty field in a database is not a "blank", as you say, but a NULL.

If it's possible to do that (and have it actually work), does that mean that
it's only on Windows (with ActiveState Perl) that Perl 5.6 and 5.8 are not

I don't think it is, or at least it wasn't installed by doing a full install

Why would you want to do something like that in Perl? When you click a
