[gradsusr] need information regarding grads operation

[Luis Blacutt]

Dear jayanti,

what you need is to add a line before
sdfwrite tot_precip

that might be
define RF=tot_precip
no spaces and the new variable name should go to the left

Then you change the final line to
sdfwrite RF
Best regards
Luis
