[gradsusr] fish_psi

[jorge.conrado at cptec.inpe.br]

      Hi,


      I have the GRADS version: 2.0.a9

      and I did:

      sdfopen uwnd_250_28012012.nc


      sdfopen vwnd_250_28012012.nc


      psi = fish_psi(uwnd,vwnd.2)


      Then I had the message:



     Syntax Error:  Invalid Operand
     'fish_psi' not a variable or function name
     Error ocurred at column 1
     DEFINE error:  Invalid expression.


     What can I do to solve this error.


     Conrado
