I was also surprised to see this in the code. What shall we call by
default then? I am not using S+ at all so have no clue. What is the
universal emacs function to start it?



Can you please check if this version works for you. If so I will commit.

(defun ess-start-process-specific (language dialect)
  "Start an ESS process typically from a language-specific buffer, using
LANGUAGE (and DIALECT)."

  (unless dialect
    (error "The value of `dialect' is nil"))
  
  (save-current-buffer
    (let ((dsymb (intern dialect)))
      (ess-write-to-dribble-buffer
       (format " ..start-process-specific: lang:dialect= %s:%s, current-buf=%s\n"
               language dialect (current-buffer)))
      (cond ((string= dialect "R") (R))
            ;; ((string= language "S") ;VS[03-09-2012]: cannot start s+?
            ;;  (message "ESS process not running, trying to start R, since language = 'S")
            ;;  (R))
            ((string= dialect "Stata") (stata))
            ;;general case
            ((fboundp dsymb)
             (funcall dsymb))
            (t ;; else: ess-language is not S

             ;; Typically triggered from
             ;; ess-force-buffer-current("Process to load into: ")
             ;;  \-->  ess-request-a-process("Process to load into: " no-switch)
             (error "No ESS processes running; not yet implemented to start (%s,%s)"
                    language dialect)))
      ;; save excursion is not working here !!! bad bad bad !!
      )))

It basically relies on the value of ess-dialect and calls the function
indicated by the dialect if such exists. Topically it is "S+6".
