David,
C-v is how you scroll one-page-at-a-time, so with numerical arguments
( "C-u 1" [ or "Cu -1" ] ),
here is how I would do it:
C-u 1 C-v for "up", and
C-u -1 C-v for "down" .
I don't know *any* lisp,
so if I found myself wanting to do this a lot,
I would probably create a macro and setup a key-binding.

You can also use M-v to scroll up.
And C-M-v to scroll down the next buffer

This might not be the most elegant... but it works... and I think it is what you have in mind...
Add these to .emacs, and try Control-Alt-n or p
;; Navigation Functions
(defun scroll-up-by-one-line()
"scroll ahead one line at a time"
(interactive)
(scroll-up 1))
(defun scroll-down-by-one-line()
"scroll ahead one line at a time"
(interactive)
(scroll-down 1))
;; key bindings
(global-set-key "\C-\M-n" 'scroll-up-by-one-line)
(global-set-key "\C-\M-p" 'scroll-down-by-one-line)

You can also use M-v to scroll up.

...how do you scroll the screen without moving point, also in the sense that
you do, say, five times C-v and then five times M-v and find the cursor in the
*same* place as it was before the first C-v...?
I found two packages that do that: pager.el and scroll-in-place.el, but the
side unwished effect is that the `next-screen-context-lines' stops working
properly in TeX and info buffers: you don't have any more the two default lines
of continuity when scrolling by screenfuls, but less, and variable.
Anyone met the same problem?
Rodolfo

I'm afraid I don't actually know the answer to this question (although
I'm sure there will be one). I was also slightly suprised when reading
it that this had never irritated me.
But then I realised what I do: Before starting to scroll, I hit C-Space
to set a mark. Then I wander round the file to my hearts content, not
even necessarily returning to where I started before hitting C-u C-Space
and being back and with point "unmoved".
Maybe this is a useful different way of solving your problem.

I wrote these years ago; maybe they will help?
(defun scroll-in-place (scroll-up)
"Scroll window up (or down) without moving point (if possible).
SCROLL-Up is non-nil to scroll up one line, nil to scroll down."
(interactive)
(let ((pos (point))
(col (current-column))
(up-or-down (if scroll-up 1 -1)))
(scroll-up up-or-down)
(if (pos-visible-in-window-p pos)
(goto-char pos)
(if (or (eq last-command 'next-line)
(eq last-command 'previous-line))
(move-to-column temporary-goal-column)
(move-to-column col)
(setq temporary-goal-column col))
(setq this-command 'next-line))))
;;;; ------------------------------------------------------------------------
(defun scroll-up-in-place ()
"Scroll window up without moving point (if possible)."
(interactive)
(scroll-in-place t))
;;;; ------------------------------------------------------------------------
(defun scroll-down-in-place ()
"Scroll window up without moving point (if possible)."
(interactive)
(scroll-in-place nil))
(global-set-key (read-kbd-macro "M-<down>") 'scroll-up-in-place)
(global-set-key (read-kbd-macro "M-<up>") 'scroll-down-in-place)
