[gradsusr] How to write data in a file

[Nick Heath]

Hey,

At the end of your script, after 'd avez' add this line..
average=subwrd(result,4)
write(test.txt,average)

When you display a variable with a single value, GrADS writes the value to the terminal in a format like this
Result value = xxxx
So, you just have to tell it to grab the xxxx part of the output.

Hope that helps!

That should do it
