[ncl-talk] Exception handling

[Gustavo Correa]

Hi Fangda

You could use the "isfilevar" function to check if the variable is in the file,
before you try to read it. 

https://www.ncl.ucar.edu/Document/Functions/Built-in/isfilevar.shtml

Strictly speaking, this is not exception handling, 
but prevents the exception from happening.

I hope this helps,
Gus Correa
