No, sorry! I totally failed to say what I was actually doing -- not checking emacs versions but checking emacs ports: I use Carbon Emacs on my mac at home, and vanilla emacs on my server, and want to set some Carbon-specific variables when I'm at home. The string "Carbon" show up in (emacs-version), that's why I was thinking that might be how I have to do it. Thanks, Eric
