[ncl-talk] Defining directories

Fri Oct 28 01:25:26 MDT 2016

Dear NCL-Talk:

I added delete(filename) to the program, but now I have another obscure
(for me) error.

Thank you for your help.

fatal:Could not coerce values for operation
fatal:["Execute.c":8578]:Execute: Error occurred at or near line 56 in file
define_dir.ncl
