Just put a backslash in front of the dollar-sign when you pass the variable to the function.
Don't forget to de-reference the variable inside the function ...
use strict;
use warnings;
my $x = 10;
&function( \$x ); # if I change $x = 5
print $x; # $x = 10
sub function {
my $x = $_[0];
$$x = 5;
} # End function subroutine

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).
