help in fwrite a data

[SUNMONU Ayanniyi]

Dear Singh,
I am a new user of GrADS that needs more help than you I think. I am just getting the information on how to use the software. I am so sorry that I can`t be of meaningful help to you now.
Meanwhile, I wish you the best in this regards and if you do get a solution, could you kindly let me into how it is solved for you for i have similar challenges.
Best regards,
