Thanks I tried this
(defun my-copy-to-buffer (buffer)
"Copy to specified BUFFER the whole buffer."
(interactive "BCopy to buffer: \n")
(let ((oldbuf (current-buffer))
(start (point-min))
(end (point-max)))
(with-current-buffer (get-buffer-create buffer)
(barf-if-buffer-read-only)
(save-excursion
(insert-buffer-substring oldbuf (point-min) (point-max))))))
And it did not work,
Your code works though.
I will never understand let
Uwe
