Re: appending data to existing Netcdf file

Hi Gary,
It's pretty straightforward to append data to a variable that has an
unlimited dimension in PyNIO.
You simply assign to the variable, referencing the index you want to
append to. If you reference an index that is greater than
the last existing index plus one, then the intervening elements will
be created and filled with whatever is the _FillValue.

I am attaching a little script that creates a file with an unlimited
dimension, defines a variable and assigns some
values, then closes it, reopens it, and assigns more elements along
the unlimited dimension.
