suppress print out from grib to netCDF scripts

Hi

I am new to NCL so I hope someone can answer to this question easily or
direct me to appropriate online documentation.

I am converting grib data to netCDF using following script (from
http://www.ncl.ucar.edu/Applications/griball.shtml). I would like to
know how to suppress verbose (it prints out all the variables in grib
files).

begin
;***********************************************
; get variable names from grib file
;***********************************************
    grib_in =*addfile* <http://www.ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml>(infilename,"r")
    names =*getfilevarnames* <http://www.ncl.ucar.edu/Document/Functions/Built-in/getfilevarnames.shtml>(grib_in); extract all variable names
;***********************************************
; create output netcdf file
;***********************************************
    *system* <http://www.ncl.ucar.edu/Document/Functions/Built-in/system.shtml>("rm out.nc") ; remove any pre-existing file
    ncdf_out =*addfile* <http://www.ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml>("out.nc" ,"c") ; create output netCDF file
;***********************************************
; loop through variables and output each to netcdf
;***********************************************
    do i = 0,*dimsizes* <http://www.ncl.ucar.edu/Document/Functions/Built-in/dimsizes.shtml>(names)-1
    ncdf_out->$names(i)$ = grib_in->$names(i)$
    end do
end

and type in terminal like
>> ncl 'infilename="/file/location/data.grb"' grb2nc.ncl

Thanks,
Naoki
