A bit longer (just a little bit) but here goes. I realise that it can probably be shortened, but in the interests of brevity and my sanity here is the longer version.
max(3,4);
sub max {
($x,$y)=@_;@xd=split//,$x;
if(length($x) != length($y))
{
return $x if(length($x)>length($y));
return $y if(length($y)>length($x));
}
@yd=split//,$y;
for($i;$i<length($x);$i++)
{
if (ord($xd[$i])!= ord($yd[$i]))
{
return $y if( ord($y)>ord($x) );
return $y if(ord ($y) >ord($x ));
}
}
}

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).

or How to display code and escape characters
are good places to start.
