When I run your code without
-w or
use strict;, I get no complaints. However, when I run it with
-w, I get your "uninitialized value" warnings, and I get the following warning:
Name "main::row" used only once: possible typo at ...
From this line of code:
$row[0], "\"", " ", $row->[4],
^^^^
Did you see this warning too?
You should fix that error and continue to use strict and warnings.
