[ferret_users] write to binary

[Sujata Mandke <amin@xxxxxxxxxxxxxx>]

Dear Ferret users,

      The following question was mailed on 
  Friday-21Sep 2012. No response, so I
  am sending again.
---------------------------

   I am trying to write daily OLR anomaly to
  binary(Grads format) file. For the first time
  I am writting to binary file, in Ferret.

  My script does following :

  Reads daily long period OLR data and 
  daily 365 days OLR climatology from
  netcdf files and calculate daily anomaly.
 Then write daily anomaly to binary file.


  I had written following script-'olran-wrtbin.jnl'

!!-----------END of FERRET SCRIPT------------------------

The script when run in ferret, ends with following error

**ERROR: unknown command qualifier: grid=gg

Please help to solve the problem.
