No, sorry....We open, read, extract our data. We have written the
following 'loop for' to open these data:

file_array=file_search('filepath', '*.200*', count=num_file)
for i=0, num_file-1 do begin
filename=file_array(i)
print, filename
openr, lun, /get_lun, filename

;read
free_lun, lun
;Analyze....
....
....
endfor

But analyze only the first file.....where do we wrong?
We hope to explain our problem....
