Hi Amadou,<br>
<br>
the error message is telling you exactly what is wrong: <br>
line 80: you try to do a calculation using variables of type string.<br>
<br>
You have to convert the variables to type integer using the NCL <br>
built-in function toint:<br>
<br>
<font color="#3333ff"><tt> dir_2100 = <b>to</b><b>int</b>(str_get_cols(split_lines,78,81))</tt><tt><br>
</tt><tt> spd_2100 = <b>to</b><b>int</b>(str_get_cols(split_lines,82,84))</tt></font><br>
<br>
Bye,<br>
Karin<br>
