        <div>How are you seeing that points convert to an area? An area
          encompassing the points?? In which case you probably want
          v.hull (<a

        <div><br>
        </div>
        <div>One further suggestion, consider changing your variable
          names for, uh, readability??</div>

    <p>v.to. lines is *not* what you want. That module takes a polygon
      and converts the boundaries to lines.</p>
    <p><br>
    </p>
    <p>If you want to go straight from the point coordinates to a
      polygon, you can use the GRASS standard ASCII format and pipe
      directly to v.in.ascii:</p>
    <pre>echo "VERTI:
