Alireza,<br>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:<br>
<br>i = 1<br>while (i <= 200)<br>'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)'<br>
(use fprintf to write data to file)<br>i = i + 1<br>endwhile<br><br>Jeff<br><br><div class="gmail_quote">On Wed, Nov 23, 2011 at 11:40 AM, Alireza Azargoun <span dir="ltr"><<a href="mailto:alireza.azargoun@gmail.com">alireza.azargoun@gmail.com</a>></span> wrote:<br>

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>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">My experience with grib2 files is to use convgrb to convert them to grib1 files, then use <a href="http://grib2ctl.pl" target="_blank">grib2ctl.pl</a> to get a control 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 href="http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file" target="_blank">fprintf</a> .<br>

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">Alireza <br clear="all">
