[gradsusr] GrADS Loop Help

[Martin V. Mathew]

Hi Emily

I have tested the script and fixed all the problems, it can now do all
required calculations. This program uses output of "q dim" command to
identify start point and end point of each month. The program uses a
compound variable to store the calculated data. Right now I don't know a
method to write values in a compound variable to a text file. Hence I am
only displaying the data to the terminal using say command. If you find a
means to write the data to text file, kindly convey it me. Please find
the attached script.

Commands 'set lon' and 'set x' do the same thing. Hence there is no need to
use both the commands.  In order to do the calculation for multiple lat/lon
coordinates you can either insert an additional while loop in the script or
otherwise change the set lat and set lon lines and run the script again.

The modified script will display output data in the terminal. Please find a
means to write the data to an output file.
