   Thanks.  After several false starts, I have a simple macro that seems to do 
   what I want:

   (defun last-sexp-other-window()
   "Get last sexp and run it in other window.
   If there isn't another window, use current window."
     (interactive)
     (setq ow-sexp (preceding-sexp))
     (other-window 1) (eval ow-sexp) (other-window -1) )

Why not use let instead of setq ?
