You can also use CarbonEmacs in a terminal, so you'll get the exact same
version in both cases.

Typically, you'll want to use things like (fboundp 'foo) to check whether
the function `foo' exists, before calling it.
Tell us more and we'll tell you more.

Hey, gang:
I'm running Carbon Emacs on OS X as my main emacs, thus my .emacs
file has a bunch of carbon only hooks in it. However, sometimes I'll
use the terminal emacs (shipped with OS X) and the .emacs file causes
problems calling things that the terminal version can't handle. I'd
like to keep the ability to use both... any suggestions for having
the .emacs file know which version is calling it and respond
accordingly?
Thanks so much for the help.
PS: I know I can forgo the .emacs file with "emacs -q", but most of
my problems occur when some other application calls emacs
automatically via the environmental $EDITOR....

IMVHO the best method is to check for the presence/absence of a
specific feature.
For example, if the problem is that sometimes a function doesn't
exist, then do
(when (fboundp 'foo)
(foo ...))

As Stefan already mentioned:
/Applications/Emacs.app/Contents/MacOS/Emacs -nw
works as well! Use it with a shell alias or a shell function.
The other option is to check (compare) the emacs major version
number. Apple's version of GNU Emacs without any windowing support is
of version 21, the Carbon Emacsen are since some time of version 22:
(cond ((< 21 emacs-major-version)
(progn
(message "This GNU Emacs is greater no. 21")
(some thing)
)
(some thing else, if needed)
)
There are more conditionals.
Could be on Leopard, the coming Mac OS X 10.5, Apple's version of GNU
Emacs will be 22. Then you could use emacs-minor-version.
There is also the symbol window-system. Without a windowing system
it's nil, otherwise one of mac, ns, x11, or ? (don't know) for MS.

Ah... thanks for the tip. Setting EDITOR equal to this in my .cshrc
resolved all problems... plus, terminal emacs is a much newer version
now. Thanks!
