Hi Martin:

I think you are mischaracterizing my remarks.  comment-dwim is
a GNU Emacs animal.  XEmacs has a variant, but it doesn't seem to
work.  Of course, M-; not working is another problem, although, I'm
hindered by the first.  However, I was able to get it to work with the
following settings, but I don't really understand what's going on:
(defvar SAS-editing-alist ...
    (comment-start                . "** ")
    (comment-start-skip           . "[*][*] ")
    (comment-end                  . " **;")
    (comment-end-skip             . " [*][*];")

Happy Holidays,

Rodney
