      I explained the problem in a wrong way. I don&#39;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 &quot;while&quot;
      is not working)<br>
      2- I need to learn how to write results and variables in a text
      file!<br>
