[gradsusr] EOF by Grads

[Chinh ta huu]

Dear all users

I am going to use Grads to implement EOF analysis. But in installed
process I have a problem as bellow:

If you never used a  User Defined Function (UDF), set your environment
variable GAUDFT to point to your  UDF table file, for example:
  csh:
 $ setenv GAUDFT $HOME/grads/udft.txt
 sh:
 $ export GAUDFT=$HOME/grads/udft.txt

I don't understand about UDF as well as GAUDFT and process to point
out UDF table. Anyone give me comments
Thank you very much
