[netCDF #KRG-880881]: Writing NetCDF 90 file with chunking

Hi Craig,

Sorry to have taken so long to respond to your question.  I'm participating in 
a conference until tomorrow ...

No, you should be able to chunk just one variable, and I know that works as I 
have done it.  However,
if you're using nccopy to chunk variables, then the chunking is specified in 
terms of dimensions, so
all variables using any of the dimensions mentioned will be chunked, but others 
left contiguous.

It's possible there's a bug that results in the symptoms you're reporting.  Do 
you have a small example
that demonstrates the problem that we could use to reproduce it here?  I may be 
able to construct one
from the snippet you provided, but a self-contained program would be better, if 
practical.
