Start with
emacs -Q
Put this into *Scratch*:
<<<<<<<<<<<<<<<<<<<<<
(defvar temp-html nil)
(setq temp-html
;; Start-here
"
<html>
<head>
</head>
</html>
") ;; Stop-here
(let ((start (progn
(goto-char (point-min))
(search-forward "Start-here")
(forward-line 2)
(point)
))
)
)
>>>>>>>>>>>>>>>>>>>>>>>>>>
With that as the current buffer then do
M-x eval-buffer
I get an error saying "Symbol's value as variable is void: <html>". Have
I done something completely wrong or?
I am doing this on w32: GNU Emacs 22.0.50.1 (i386-mingw-nt5.0.2195) of

Yes, replace progn by save-excursion. You have modified point under
eval-buffer's feet, it will continue evaluation until point equals
point-max.
