[gradsusr] how to operate

[happysarsar]

Hello,

I am a new grads user. I already prepare data file(.gad)
And also prepare requirement file for grads.
But I don't know how to run the grads.
My problem is I cannot open my data file of (.gs )file in grads.
I found this running program .Firstly , grads file asking to me ,landscape
or portrait.
Then already entered ga-> ,after I chose of landscape.
After that I opened my file but..cannot read.
So, how can I do? Please write me the step of running procedure.

Thanks a lot.
