[gradsusr] HELP TO OPEN FILES

[Mohsen Soltani]

Hi Arturo,

You need to define each file, no matter how many files you're gonna open!
Based on your script, you have 3-variables. Therefore, do as follows:

******************************************
'sdfopen D:/NETCDF/LEVEL_PRESURE.nc'
     'set dfile 1'
*
*
*
*
*
*
'display pres'
*************
'sdfopen D:/NETCDF/USURFACEWIND.nc'
     'set dfile 2'
*
*
*
*
*
'display uwnd'
******************
'sdfopen D:/NETCDF/t_mar2003.nc'
    'set dfile 3'
*
*
*
*
*
'display (air-273.4)'
**************************************

Good luck,
Mohsen
