'getenv' behavior in NCL not as advertised...

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.
