When I place an if statement with in any type of loop it appears as though that if statement will only evaluate once regardless of how many loop iterations. How would I be able to loop multiple times, evaluate some condition multiple times, and execute code multiple times based on the condition? Here is an example of what I'm trying now (this guy has one nest loop and if statement. It appears once the if statement is true Perl won't evaluate it again: 
foreach(@class) 
{
    ($id, $name, $credits) = split(/,/, $_);
    $x=0;
    while ($clen > $x)
    {
        if ($course[$x] eq $id)
        {
        $z++;
        
        }

        $x++;
    }

}
