Re: NCL Version 6.0.0 now available

Hi Robert,
'group' is a new variable type that represents a portion of a file for formats such as HDF5 and NetCDF4 that support this concept.
It is not fully documented yet and is still undergoing development. We hope to have more documentation soon.
But just so you know, given a file type variable, 'f', that references a file containing the top level group 'mygroup', you can create a group variable, 'g', using:
 
g = f=>/mygroup ; notice '=>' in place of '->'

It is pretty much like a file type variable in that it can have group-level attributes and contains variables and/or other groups.
