[ncl-talk] Reading str_split_csv function

[Karin Meier-Fleischer]

Hi Amadou,

the error message is telling you exactly what is wrong:
line 80: you try to do a calculation using variables of type string.

You have to convert the variables to type integer using the NCL
built-in function toint:

   dir_2100       = *to**int*(str_get_cols(split_lines,78,81))
   spd_2100       = *to**int*(str_get_cols(split_lines,82,84))

Bye,
Karin
