The <fetch> statement, given a URL, fetches that page on the Web and returns it:

  <SCRIPT LANGUAGE=vortex>

  <A NAME=main PUBLIC>
    <FORM METHOD=post ACTION="$url/">
      Enter a Url: <INPUT NAME=page SIZE=40 VALUE="http://">
      <INPUT TYPE=submit VALUE="fetch">
    </FORM>
    <IF $page neq "">
      <H2>Here's the link text</H2>
      <fetch $page>
      <rex ROW "<a=[^>]+>\P=!</a>*" $ret>
        $ret <BR>
      </rex>
    </IF>
  </A>

  </SCRIPT>
