I believe you want either [Text::Wrap][1] (which has been a part of the core since Perl 5.2): #!/usr/bin/perl use strict; use warnings; use Text::Wrap; my $var = 'American Express offers individuals online access to its world-class Card, Financial, and Travel services, including financial advice, retirement planning, air and hotel reservations and more'; my $indent = " " x 4; $Text::Wrap::columns = 70; print wrap($indent, $indent, $var), "\n"; [1] : http://perldoc.perl.org/Text/Wrap.html -- Chas.
