You don't need GrADS to do that ..<br>
use wgrib2 to do it, I use it just like your describing<br>

I explained the problem in a wrong way. I don't have any problem
with opening the files. i used g2ctl and gribmap( I already
created CTLs and IDXs for all files) and I can easily read data
from a file or maybe 10 files. but there are 200 files. and I need
a :<br>
1- while loop to open the files. ( can anybody tell me why "while"
is not working)<br>
2- I need to learn how to write results and variables in a text
file!<br>

experience with grib2 files is to use convgrb to
convert them to grib1 files, then use <a

file for each converted grib1 file. You can do that
using a C-shell loop. Once you do that, you can use a
while loop in a Grads script (not at the command
prompt), to open each individual file and print the
data to a text file using <a moz-do-not-send="true"

Dear GrADS users<br>
Hi everybody<br>
<br>
I have about 200 grib2 files ( 1.grb2 ~
200.grb ) . i need to read a temperature of a
city (lat, lon, lev, time are constant in all
files) . how i can read this files using a
while loop!? ( I receive this error when i
write a while. Unknown Command: while )<br>
and how can i write these data to a text
file!? I've searched all grads option for a
command that writes variables in a text file!
but i couldn't find it!<br>
<br>
Thanks in advance,<br clear="all">
