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

["Paulo B. Oliveira" <pbo@xxxxxxxxx>]

Hi,

I'm trying to save a local subset of NCEP Climate Forecast System
Reanalysis (CFSR) data. 

Everything goes fine except for the variables containing the symbol '-'
in the name: 

use
"http://nomads.ncdc.noaa.gov/thredds/dodsC/cfsrmon/200912/ocnh06.gdas.200912.grb2";
set reg/x=350:352/y=36:42
save/file=ocnh06_200912.cdf Temperature   !================ OK!
save/file=ocnh06_200912.cdf U-component_of_current !======= **ERROR:
variable unknown or not in data set: COMPONENT_OF_CURRENT

Any hints ?

Paulo
