From menu button, how run more than one command?

[DiGrazia <rjjd@localnet.com>]

I want to have a menu whose buttons each executes something like this:

(cd "c:/blah/")
(find-file) ;Do not specify file; instead, open the Find File window.

That is, I want each button to run "cd" and then "find-file" interactively.

The code below works, but note that the menu button calls function
"abc".  If the menu contains many buttons, each button would need a
dedicated function.

(defvar my-menu (make-sparse-keymap))

(define-key my-menu [rmx]
   '(menu-item "FILE" abc))      ;executes function abc

(defun abc ()
   (interactive)
   (cd "C:/emacs")
   (call-interactively 'find-file)
)

Is there a way to write the "define-key" so that I don't need a separate
function?
Or, is there a way to pass an argument from "menu-item" to a function?
