Poor man's programming, don't encourage him to start with
that :)

This is a very simple task to solve with Elisp and the problem
with the point position is easily solved by either putting the
point at the correct position before invocation (this method
allows for bigger flexibility) _or_ but using
`save-mark-and-excursion' and `goto-char' to put point at
`point-min'.

This is also a good candidate for a DWIM interface:

(defun test-dwim (&optional beg end)
  (interactive (when (use-region-p)
                 (list (region-beginning) (region-end)) ))
  (let ((bg (or beg (point-min))) ; or just (point) here
        (ed (or end (point-max))) )
    (list bg ed) ; code here
    ))

If you get the point ...
