access to Unix environment variables from within grads scripting language

[Diane Stokes]

My mistake.  It only looked like it was working.  ...Sloppy on my part.

From:  http://grads.iges.org/grads/gadoc/gradcomdshell.html

"If the shell command is executed from a Grads script, the output will
not [be] returned as a string buffer to the script."

Sorry to get your hopes up.
