Re: Auto Fill Comments

[Christopher Dimech]

I am getting somewhat confused because I have also seen
people using set-fill-column and setq-default.

Is doing fill-column and set-fill-column the same thing?


(add-hook 'text-mode-hook
   '(lambda()
       (turn-on-auto-fill)
       (set-fill-column 72) ))

(setq-default fill-column 72)
