Hi,

I have these questions about the NCML Language :

- I know that it's possible to modify the values of data variables 
explicity using the element <values start=.. increment=..>. 


- For just confirmation, is it possible to modify the data variables 
directly without inspecting these values ? (I think that it's not possible) :

For example :
-----------------

- inverse the data variable 
directly without inspecting its values ?
 for example :
   lat[lat] = 90, ... , 0 , ... -90 -> ncml -> lat[lat] = -90, ... , 0 , ... 90
  This implies also the modification of values of the Grid Variables ( 
SST[time][lat][on], for exampe) 


- modify the values of the longitude :
     lon[lon] = -180, ... , 0 , ... 179 -> ncml -> lon[lon] = 180, ..., 365 , 0 
, ... 179
   There are no changes in the values of the Grid variables  ( 
SST[time][lat][on], for example) 
 
Thank you in advance.
