[ncl-talk] convert string to variable name

[Adam Phillips]

Hi Zhifeng,
The short (unfortunate) answer is no, you cannot use dynamical variable
names. This is a commonly requested feature. If you search for "dynamic
variable naming" on the NCL website you will see a few of the ncl-talk
queries on this subject and you can see if any of those responses can
assist.
Hope that helps.
Adam
