Re: how to get user input

Joe,

I do some of this in a separate shell script. I've not found any
indication that you can communicate in the manner you're asking about
from within NCL (and Dennis' comments confirm this).

I have several scripts where a lot of the "intelligence" happens in the
shell portion, and then sends the CLAs to the NCL script. For me, this
has been very successful.
