Re: ^M problem

Jean,

Thanks for the info. However, I can't change the file, so, I want to change
how emacs _displays_ the file.

When it displays lots of ^M's it usually means emacs chose UN*X mode
instead of DOS mode. I'd like to dynamically change that mode back to DOS
mode, when it happens.

It's simply that sometimes it makes the wrong choice between UN*X and DOS
mode. Next time it happens, I will play a bit with the buffer-file-*
variables, mentioned below...

I usually use the tool fromdos to overcome this. if you are using debian
you can get it
by apt-get install sysutils

and use fromdos filename. This will take care of it.
