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.
         (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:")
         (delete-other-windows)
         (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
