[gradsusr] smoothing large resolution data

[wendi harjupa]

Dear Mr Andrew,

Many thanks for your response

There is no specific error, but the is no change of result when I use
'd lterp command'.

I set my dimension environment as below :

    'set lat 33.000  36.000'
    'set lon 134.000  137.000'

I am little confused how to use the 'd lterp'  function in my script
program.

Would you mind to give me more clue?

Best regards,
wendi
