Line 4 assigns an anonymous hash ref to value. You do not need any quotes
at all. and the fact that it is looking for $startloc would suggest that you
are using single quotes around '$startloc' in your open statement which is
incorrrect. I would suggest backing up and learning the basics first. You
will save yourself much time and aggravation in doing so.
