You can use the 'save' procedure to save the data to an IDL .sav file.

The printf command will write data to a file in the format you specify. You probably want to be using save rather than printf, if I undertstand your posts correctly. See: http://www.exelisvis.com/docs/SAVE.html

If you're talking about saving an actual plot, rather than the data in it, that's a different question. If you want a jpeg or png then IDL has routines for that, e.g.: http://www.exelisvis.com/docs/WRITE_PNG.html (you'll also need to use tvrd before.)

If you want eps/pdf output then that involves a little more typing but is also pretty straightforward.

As to looping over files, you can do something like:

files=file_search(my_folder+'*.myformat',count=nfiles)

if nfiles gt 0 then begin
for i=0l,nfiles-1 do begin
(do your stuff here)
endfor
endif

Hope this helps,

Andy
