Toggle line length?

Toggle line length?

[-- Attachment #1: Type: text/plain, Size: 427 bytes --]

I have my line length set to 74 with this - (setq-default
fill-column 74). Is it possible to be able to toggle this so that I
could have an alternative line length of 100 please? I've been
googling but without success.

Thanks
Sharon.

(defvar my-last-fill-col 100 "...")

(defun my-toggle-fill-column ()
  "..."
  (interactive)
  (setq-default my-last-fill-col
                (prog1 fill-column
                  (setq-default fill-column  my-last-fill-col)))
  (message "Fill column is now %d" fill-column))

Thanks Drew, that’s working very nicely, and thanks for the
speediness! :)

How can I make the line-length of the complete buffer to be 100
please? Again toggling back and forth with 74.

I'm writing a latex document, and 74 seems so short whilst I'm in
the thick of it, so I'm wanting to try out 100. 

Sharon.

Sorry, I don't know what you mean.  What is "the line length of
the complete buffer"?

I mean that the same line-length of 100 is seen throughout the whole
buffer. Whilst other open buffers remain at 74.

Thanks

`fill-column' affects the whole buffer.

I thought you wanted to change the _default_ value of `fill-column'
each time you toggle between 100 and 74, because you mentioned
`setq-default'.

But you can also use just `setq' in that code, to toggle the value
only for the current buffer.

I think they mean window width.

Then this all means nothing to me; sorry.
