   Microsoft Excel   Adjustable cells   Constraints
   version
   ---------------------------------------------------

   3.x               200                299
   4.x               200                500
   5.0               200                500
   7.0               200                500
   97                200                unlimited/500*
   98                200                unlimited/500*

  constraints you can use is unlimited. If you are working with a
  nonlinear problem, the maximum number of constraints you can use is 500.
