[ncl-talk] Bug in ncl

[Adam Phillips]

Hi Mathieu,
Thank you for sending in a short script showing the error. I can reproduce
your results using v6.3.0.

The instances of the ARSCAM/ARPRAM error have been dramatically reduced,
but not 100% eliminated, since v5.2.1. See the FAQ here:
http://www.ncl.ucar.edu/FAQ/#err_msgs_015

I was able to get your Bug.ncl script to work by setting cnFillMode =
"RasterFill" and replacing res at cnSmoothingOn = True with
res at cnRasterSmoothingOn = True.

If you still get an error after making the suggested resource changes let
ncl-talk know.
Adam
