limiting line length

[Molitor, Stephen]

This may be more of a Emacs than a JDE question, but...

We have a coding standard that says lines shall not be more than 80
characters long.  Is there any way to limit the line length some how?  Maybe
by automatically wrapping after x characters?  Or maybe just vertical line
down the screen at char 80 to let you know when a line is to long? Or
setting the screen frame width x characters (not x pixels)?  Or something?

Thanks!
