Add static word wrap line

Add static word wrap line

[Alexander]

Hello.
I'm using GNU Emacs 23.0.60.2.
How can i add a static word wrap line - A vertiacal line for example at 
the eightieth symbol of the line.
Thanks.

As far as I know there's no way to draw such a line.  There are ways to
highlight characters beyond that line, including the package I actually
just released today:

http://nschum.de/src/emacs/highlight-80+/

You can find more ways here:
http://www.emacswiki.org/cgi-bin/wiki/FindLongLines#ShowLongLines

and maybe here:

Maybe vline et al can be useful too - even if they do not do exactly 
what Alexander wants. (Maybe they can be a start for making something 
like it?)

Indeed.

Although it has some problems.  The line appears with the cursor at the
end of a line, and `beginning-of-buffer' doesn't redraw the line.

I hope someone picks this up.

What do you mean by "vertical line"? Are you just looking for a displayed
vertical line, to remind you of the word-wrap column?

If so, there are solutions here:
http://www.emacswiki.org/cgi-bin/wiki/HighlightCurrentColumn.

They let you display a vertical line at any column. By itself, this display
artefact has no effect on word-wrap. But you can use the same column (e.g. 80)
for word-wrapping.
