If you wish to avoid any modules, you can do it this way:
#!/usr/local/bin/perl
use strict;
use warnings;
my $var = "this is just a sample of a string, there is nothing really
+important in the scalar, just a lot of text";
my $pos = 9;
while(( $pos = index($var, ' ', $pos)) > -1 ) {
substr($var, $pos, 1) = "\n";
$pos += 10;
}
print "\n$var\n";
Just remember, TIMTOWTDI.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
