'Z':     </pre>   <p><strong>Be careful:</strong> Write spaces around the <code>...</code>, for otherwiseit may be parsed wrong when you use it with integer values.  For example,write this:<pre class="smallexample">     case 1 ... 5:     </pre><p>rather than this:<pre class="smallexample">     case 1...5:     </pre>   </body></html>
