[ncl-talk] Help with copying array into a larger array

[Mary Haley]

Hi Laura,

For reasons I don't understand right now, it doesn't like that one variable
has a "lat" dimension, while the other one is "lat2".

If you rename the data "lat2" dimension to "lat" before you do the copy, I
think it should work (I tried it on a small test program).

data!1 = "lat"
