Re: [ferret_users] How to get "illegal" var names from opendap server

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Paulo,
You can use the variable puting the name in single-quotes.

   save/file=ocnh06_200912.cdf 'U-component_of_current'

This is documented under "Netcdf, variables, invalid names" in the Users 
Guide index,
http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/variables-xpressions/VARIABLES#_VPINDEXENTRY_244

I'll work on adding some more references so that one might find the 
information more easily.

Another thing you could do is the trick of renaming the variables when 
you open the dataset,

   use "http://nomads.ncdc.noaa.gov/thredds/dodsC/cfsrmon/200912/ocnh06.gdas.200912.grb2";
   set var/name=U_component_of_current 'U-component_of_current'

and then save the variable using the new name, so that future use of 
your local file in Ferret wouldn't require the quotes.
