[ncl-talk] how to process string variable

[Ming Chen]

Hi Dennis,

Thanks for the answer, which solves my problem. However, I am still 
curious why the Fortran code doesn't work and how I can make it work. I 
ask this because I heavily rely on Fortran to process some in-situ 
observations, which includes both numbers and strings. I hope to 
understand more about the combination of Fortran with NCL.

Thanks again.

Ming
