With script variables, you would indeed use "define".

That is:</div><div><br></div><div>"d lon"</div><div>lonw = subwrd(result,<leftmost character position>, <rightmost character position>)</div><div><br></div><div>where leftmost and rightmost refer to the left and right position in the line that includes the variable lonw.</div><div>If there are multiple lines in the display, you'll have to first choose the line that contains the longitude.
