Thanks, Emanuel and Rusi. GT signs are there because I copypasted out of
gnus.help where I posted by mistake. I should have stripped them.
I now have:
Not exactly what you do but for the same reason I have:
(defun save-scratchtemp ();; M-x sch
(interactive)
(save-excursion
(with-current-buffer "*scratch*"
(mark-whole-buffer)
;;(setq start (point) end (mark))
(append-to-file nil nil "c:/mydocu~1/scratchtemp.txt")))
)
which also "works." Also I may not need save-excursion even if my
current buffer is not *scratch*. I used nil nil for start, end maybe
unnecessarily if append-to-file renumbers the argument list.
I think that the add-hook won't work for me:
(add-hook 'lisp-interaction-mode-hook
(function (lambda () (setq buffer-offer-save t))))
because *scratch* would have to be associated with a file name which
would replace the *scratch* buffer. My kludge is pretty hokey but at
least I understand it and the multiple copies of the same -short
stretches of text won't be a cumulative problem if I just delete the
scratchtemp.txt file now and then.
