emacs variables and Win Environment Variables

["Javier Oviedo" <email_joviedo@yahoo.com>]

Hello all:

Can emacs recognize and use Windows environment variables? For example...

I currently use hard coded paths in these tow cases:

(setq load-path (cons "C:/data/joviedo/Emacs/site-lisp_21_2" load-path))

(defun my-load-DOTemacs ()
  (interactive)
  (find-file "C:/data/joviedo/emacs/_emacs21_2"))


Instead, I'd like to use:

(setq load-path (cons "%MY_EMACS_PATH%/site-lisp_21_2" load-path))

(defun my-load-DOTemacs ()
  (interactive)
  (find-file ""%MY_EMACS_PATH%/_emacs21_2"))

Obviously, I would define MY_EMACS_PATH as a valid path. I prefer to use a
windows environment variable, if possible...but I'd be open to using some
sort emacs global variable or #define like mechanism. My goal is to not have
hard coded paths and such things. I personally hate going in and modifying
these things in every location. I'd like one central place to make the
modification.

Thanks in advance for any assistance.
