You have been given great answers, but If I may add just this. Using a subroutine with scalar, reverse functions with substitution s///. One can hack a solution like so:
use warnings;
use strict;
my $foo = "1,2,3";
print modify( $foo, ',', '|' ); ## prints 1,2|3
$foo = "1|2|3";
print modify( $foo, '|', ',' ); ## prints 1|2,3
sub modify {
my ( $val, $sep, $rep ) = @_;
$val = scalar reverse $val;
$val =~ s/\Q$sep\E/$rep/;
return scalar reverse $val;
}
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

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).
