w32-shell-dos-semantics

[Rodney Sparapani]

ess-help:

Without getting into a debate, I wouldn't recommend downloading all of these functions and attempting to run them under xemacs.  Many FSF lisp files will work with xemacs, but 
some won't and it can be a hair-losing scenario.  Since the original poster is interested in R, Tony's solution is probably best.  As it currently stands, I have never been 
able to get ESS for SAS to work effectively in xemacs under either Unix or Windows.  There's a quick fix for this particular function and two for a common side-effect under 
Windows (but, they don't get everything to work, unfortunately):

(if (featurep 'xemacs)
  (defun w32-shell-dos-semantics ()
  "Return t if the interactive shell being used expects msdos shell semantics."
        (or (string-equal "COMMAND.COM" (file-name-nondirectory shell-file-name))
            (string-equal "CMD.EXE" (file-name-nondirectory shell-file-name)))))


(defvar explicit-command-args nil
   "Switches for COMMAND.COM.")


(defvar explicit-cmd-args nil
   "Switches for CMD.EXE.")
