Bittna,


The function (dired-get-marked-files) looks interesting.

I don't speak lisp well, so this mightn't be the best way of doing things.

(loop for fileName in (dired-get-marked-files) do
(progn
    (find-file fileName)
    (bittna-lisp-expr)))


or

(loop for fileName in (dired-get-marked-files) do
  (let ((buff))
    (progn
     (setq buff (find-file fileName))
     (bittna-lisp-expr))
     (kill-buffer buff)))




I use XEmacs, rather than GNU Emacs, so YMMV.

HTH,
Colin S. Miller
