Hi Dongdong:

note that you CANNOT select the path to the eofudf.in/out files. It is
hard coded into eofudf to be the current directory. Please make sure
your udft.txt entry for eofudf looks like this:

- -----------------8<--------------
eofudf 2 6 expr value value value value char
sequential
/climate4/chdd/GrADS/UDF/eofudf
eofudf.in
eofudf.out
- ----------------->8--------------
