[gradsusr] HELP TO OPEN FILES

[Abatan Abayomi]

Arturo,

In which of the files is air and uwnd? If for example the variable air is
located in file 2, then you need to type:

 'display (air.2 - 273.4)',

and if uwnd is located in file 3, then type:

 'display uwnd.3'

Hope that work for you.

Abayomi
