It's up to you how you want to deal with it.  Right now it is something like:

   $data = substr($line, $arr[0], $arr[1]-$arr[0]);

You could do:

   $data = substr($line, $arr[0]-1, $arr[1]-$arr[0]);

Then where you signify the first character as 1, this line will subtract 1
for you and make it the actual position 0, which is what you want.  Or you
could mess with $[, but as perlfunc says, "don't do that".  :)
