thanks for answering, i am afraid my question was not that clear;
the problem is infact to do the task using IDL commands in order to
batch the process (i have a huge amount of files to convert); which are
the commands i should use ?
thanks

I have a short program that can be used to batch process files.
------------------
function file_rep, filelist, func
openr, file_lun, filelist,/get_lun
filename=''
while NOT EOF(file_lun) do begin
readf,file_lun,filename
a=call_function(func,filename)
endwhile
free_lun, file_lun
end
--------------------------------------
To use this, first create a file containing the list of files you would like converted. You will also need to write a function
that takes a single file name as it's argument and does the processing you want on a single file. So, you would use this
function something like this:
IDL> dummy=file_rep('filelist','ascii2envi')
You will need to write the ascii2envi.pro function.
Hope this helps,
