IDL and GRIB [message #94025]

Dear all,

I'm trying to run the following IDL code:

--------------
pro read_grb2

file = FILEPATH('atl.grb2', $
SUBDIRECTORY=['examples','data'])
;FILE_COPY,file,dir+'atl.grb2'
GRIB_LIST,dir+'atl.grb2'

record = ORDEREDHASH()
record['GRIBEditionNumber']=2
record['values'] = dblarr(1024)
GRIB_PUTDATA, dir+file, record

end
--------------------------

It should add "record" to the grib file atl.grb2 (that was copied in my home directory).
When I run the code I get the following error:

% Loaded DLM: GRIB.
% Compiled module: GRIB_LIST.
1 crain DOUBLEARRAY[141151]
2 usct DOUBLEARRAY[141151]
3 vsct DOUBLEARRAY[141151]
4 tsec DOUBLEARRAY[141151]
% Compiled module: GRIB_PUTDATA.
% GRIB_PUTDATA: GRIB_SET: Value is read only
% Execution halted at: READ_GRB2 123
/Users/stefano/fdgrib2/read_grb2.pro
% $MAIN$

I cannot understand the reason for this error. Does anybody have an idea?

Thanks

Stefano
