Opps, the code I posted earlier confused the HTML syntax. Here's the complete code reposted...

for (589840, 117506056, 134225920, 671555840,
     534280, 1058576, 654911248, 151718157, 
     269160461, 168496907, 168627981)
{
    ($x, $y, $v, $w) = unpack "c*", pack "l", $_;
    $e = $v - $x; $g = $w - $y;
    $h = abs $e; $k = abs $g;
    $d = $h > $k;
    for (0..(($d) ? $h : $k))
    {
        $f += $d ? $g/$e : $e/$g;
        $f1 = $f;
        int $f && do
        {
            $y += $d ? ($g > 0 ? 1 : -1) : 0;
            $x += $d ? 0 : ($e > 0 ? 1 : -1);
            $f += $f > 0 ? -1 : 1
        };

        $c[$y] ||= ' ' x 60;
        substr($c[$y],$x+1,1) = abs $f1 >= 1 ?
               $f1 > 0 ? "\\" : "/" : $d ? "-" : "|";
        $d ? ($x += $e>0 ? 1 : -1) : ($y += $g>0 ? 1 : -1);
    }
}
$" = "\n";
print"@c\n";

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
