[Tutor] Assigning a variable to an FTP directory listing

[Pat Martin]

Below is what worked for me, thank you. I had a feeling it had to do
with the callback but have never dealt with callbacks before so wasn't
sure. Time to do more reading.

For those asking about alternatives to FTP, its for a vendor who only
uses FTP so no choice in that.

Thanks all for the help.
