    According to http://ngwww.ucar.edu/ngdoc/ng/ref/ncl/functions/getenv.html,

    "The getenv function returns either an empty string when the shell environment
    variable does not exist, or the string value of the environment parameter
    requested."

    However, if I do a getenv on an undefined environment variable, I get a fatal
    error:

    fatal:getenv : (NDAYS) is not a defined environment parameter

    Something of a curioisity.
