any Emacs features to help keep code/comments under 80 columns width?

[seberino]

I often write comments and code and look at modeline's Column# display
to verify I did not go beyond the 80th column when I type.

Are there any goodies in Emacs to help me accomplish this???


Maybe....

1. Emacs flashes the screen when I reach column 80

2. Emacs automatically adds a hard return and moves me to next line
   when I reach column 80.

3. Emacs just doesn't let me type beyond column 80.
