I think what you rather want is an array called @bin

use strict;
use warnings;

my $counter=0;
my @bin;
while( my $line = <> )
{
  $counter++;
  $bin[$counter] = $line;
}

see perldata#List-value-constructors for details on arrays (numbers as indices) and hashes (strings as keys)

and please always use

use strict;
use warnings;
