Hi,all:
I am reading Emacs Lisp Intro.
There is one fuction:
(defun append-to-buffer (buffer start end)
"Append to specified buffer the text of the region.
It is inserted into that buffer before its point.
When calling from a program, give three arguments:
a buffer or the name of one, and two character numbers
specifying the portion of the current buffer to be copied."
(interactive "BAppend to buffer: \nr")
(let ((oldbuf (current-buffer)))
(save-excursion
(set-buffer (get-buffer-create buffer))
(insert-buffer-substring oldbuf start end))))
I want to know how can I use it?
Thank you.

I just didn't know how to pass the two number argument(START and END)
after "<ALT> x".
With your advice, I understand, just use mouse to "create" the "active
mask" in oldbuf, then do "<ALT> x append-to-buffer buffer".
It works now.
Thank you!
