Hi Soma,<br>
<br>
if the file example.nc already exists NCL can't create a new one
with the same name. You have to remove the file, first.<br>
<br>
<font color="#3333ff"><tt> filo = "example.nc"
; Output file</tt><tt><br>
</tt><b><tt> system("rm -rf "+filo)</tt></b><tt><br>
</tt><tt> fout = addfile (filo, "c") ; open output
file</tt><tt><br>
</tt></font><br>
