21.2.3 Examples of Using interactive

Here are some examples of interactive:

(defun foo1 ()              ; foo1 takes no arguments,
(interactive) ; just moves forward two words.
(forward-word 2))
⇒ foo1
(defun foo2 (n)             ; foo2 takes one argument,
(interactive "^p") ; which is the numeric prefix.
; under shift-select-mode,
; will activate or extend region.
(forward-word (* 2 n)))
⇒ foo2
(defun foo3 (n)             ; foo3 takes one argument,
(interactive "nCount:") ; which is read with the Minibuffer.
(forward-word (* 2 n)))
⇒ foo3
(defun three-b (b1 b2 b3)
"Select three existing buffers.
Put them into three windows, selecting the last one."
    (interactive "bBuffer1:\nbBuffer2:\nbBuffer3:")
(split-window (selected-window) 8)
(switch-to-buffer b1)
(other-window 1)
(split-window (selected-window) 8)
(switch-to-buffer b2)
(other-window 1)
(switch-to-buffer b3))
⇒ three-b
(three-b "*scratch*" "declarations.texi" "*mail*")
⇒ nil
