Amy, I'm not a Perl guru, but I'd basically use this in a loop so that
I keep reading the next 30 (in your case it's 250) characters.

use strict;
use warnings;

my $string = 'Eduardo Bacchi Kienetz lives in Santa Maria, Rio Grande
do Sul, Brazil.';
my $piece =  substr $string, 0, 30;
my $beforespace = substr $piece, 0, rindex($piece,' ');
print $beforespace . "\n";
