[R] Configuring ESS for SAS on Win NT & Win 2000

[Brett Presnell]

I should start by confessing possible ignorance about using SAS
interactively.  I don't use SAS interactively, and the last time I did
use the SAS interface, I wouldn't have said that it was interactive in
any meaningful sense of the word anyway, just an editor and windows to
look at the log and out files and so forth.  Maybe that has changed
without my knowledge.

Anyway, the way I work with SAS under UNIX is to edit the code using
ESS and then execute it using dired's dired-do-shell-command, which
just require positioning the cursor over the .sas file in the dired
listing and typing an exclamation point (!) and return.  Then I move
down to the log and out files to see what I got (just type "f" to open
a file in an emacs buffer).  It doesn't take much to get pretty fast
with this and it works very well for me (my students are always
impressed).

To make this work, you need something like the following in your
.emacs file:

(setq dired-guess-shell-alist-user
	  (list (list "\\.sas$" "sas")))

Actually, my dired-guess-shell-alist-user is much longer than this,
because I use dired all the time and I like to be able to type ! to
"open" pdf files and whatnot.  Dired is actually a pretty good "file
manager" and like most things emacs, the more you use it the more you
learn to do with it.  Lots of people on this list probably know more
about this than I do, but FWIW I've appended below what I actually
have in my .emacs for dired mode.
