Systemfunc Not Working

Dear NCL-Talk,

Suddenly, I cannot use "systemfunc" within NCL. I just get missing values
returned in the NCL scripts that I've used for years. I running version
6.0.0.

ncl 0> print(systemfunc("date"))

*Date works in the terminal:*

Any idea what could have happened and how to fix it?
