Are you using warnings and strict? The code fragment you posted shows  use warnings; but the following suggests it's not used | there or has been disabled: 

c:\@Work\Perl\monks>perl -wMstrict -le
"my $index;
 $index == 0;
 ;;
 my @ra = qw(foo bar);
 print $ra[$index];
"
Useless use of numeric eq (==) in void context at -e line 1.
Use of uninitialized value $index in numeric eq (==) at -e line 1.
Use of uninitialized value $index in array element at -e line 1.
foo

[download]

use warnings; and  use strict; may help you find many instances of questionable code.

Another question comes to mind about the 'download' method you are using. If a text file is downloaded via a channel that automatically corrects line endings (e.g., cr-lf versus lf), the file will visually appear unchanged, but a binary file may be (almost certainly will be if it's big enough) corrupted. If you're using FTP, are you using ascii or binary mode?
