Alireza,
Well, as I said, use that fprintf program I linked to you in my previous
email.  You can copy it to your own file system and make it a script.  The
script has help text to tell you how to use it.  As far as opening the
files using a while loop, use the following code within a Grads script:

i = 1
while (i <= 200)
'open (filename that has something to do with the index i.  This can be
either a string array with index value i or some literal value that
involves i that is part of the filename)'
(use fprintf to write data to file)
i = i + 1
endwhile

Jeff
