Greetings all,
Here is my suggested solution:
#!/usr/bin/perl -w
use strict;
my $string = "ABCDEFGH";
print $string."<= before\n\n";
my $regexp = '\w{'.int(length($string)/2).'}';
$string =~ s/($regexp)/$1-/;
print $string."<= after\n\n";

exit;

[download]

It outputs: 
ABCDEFGH<= before
 
ABCD-EFGH<= after

However this assumes you wanted to split the string in half.
Just a thought

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
