Hi all:

I'm trying to read the data from a variable in reverse order.  Say I
have a 1-D variable of length ten, so start=0, count=10, stride=1 in
nc_get_vars gives me all the data.  I though perhaps start=9,count=10
and stride=-1 would give me the data in reverse order, but I get a
'Illegal stride' error.  Am I missing something simple, or is this not
a supported operation?

Jeff,

I think you may want to try the varm functions
(i.e. nc_get_varm_<TYPE>).

What you are trying is not a supported operation, as I understand it.
