[OS X Emacs] Re: How to call "call-process"

[siemsen at ucar.edu]

Thanks!  Here's what I'm using now:

; bind Command-Shift-7 to execute PetesLookup and feed it the highlighted string
(define-key osx-key-mode-map (kbd "A-&")
  (defun execute-PetesLookup ()
    "Execute PetesLookup, feeding it the current selected region as a command-line argument."
    (interactive)
    (call-process "/Users/siemsen/Applications/PetesLookup.app/Contents/MacOS/PetesLookup" nil nil nil
                  (buffer-substring (point) (mark)))
    )
  )

This works and is clearly better, but it smells funny to define a named function when the name is never referenced.  Is there a way to just invoke call-process, without a defun?
