Area lisp not working in AutoCAD 2015

Can anyone make this work in AutoCAD Map3D 2015 release?

It has worked fine in all previous versions of AutoCAD Map3D, prior to 2015.

;;This program will calculate the area of irregular polygons
;;by picking an area inside the polygon.
(defun C:AUTOAREA (/ ar en n num pt ss1)
  (if (not "acadapp.exp")(xload "acadapp.exp"))
  (setq n 0)
  (setq ss1 (ssadd))
  (while (setq pt (getpoint "\nSelect internal point:"))
     (bpoly pt) ;;ADS function
     (setq ss1 (ssadd (entlast) ss1))
  );;while
  (setq num (sslength ss1))
  (command ".area" "a" "e")
  (while (/= num n)
     (setq en (ssname ss1 n))
     (command en)
     (setq n (1+ n))
  );;while
  (command "" "")
  (command "erase" ss1 "")
  (command "redraw")
  (princ "\nThe area of the polygon in hectares is: ")
  (princ (cvunit (setq ar (getvar "AREA")) "SQ METER" "HECTARE"))
  (princ "\nThe area of the polygon in acres is: ")
  (princ (cvunit (setq ar (getvar "AREA")) "SQ METER" "ACRE"))
  (setq ss nil)
  (prin1)
);;end autoarea.lsp

Like other posts change COMMAND to Command-s or VL-cmdf definately required for 2016 etc

I don't know LISP at all, but I found and replaced "command" with "command-s" and that made no difference. I don't know anything about VL-cmdf...
