    Hi Lyndz,<br>
    <br>
    In case you haven't received a reply, this is what I have used.  You
    click the mouse on the location, and the lat and lon come back.<br>
    <br>
    Good luck!<br>

        say 'click to locate center'<br>
        'q bpos'<br>
        x = subwrd(result,3)<br>
        y = subwrd(result,4)<br>
        'query xy2w 'x' 'y<br>
        xlat = subwrd(result,6)<br>
        ylon = subwrd(result,3)<br>
        say xlat ' 'ylon<br>
    *   now we have the lat and lon of the cursor<br>
