Stack Checking                     {$K+}                             pp 317

 Default:   Active

 Scope:     Local

 Active:    {$K+}  Stack space is checked prior to subroutine call.

 Inactive:  {$K-}  No stack checks are made


 ----------------------------------------------------------------------------


 Notes:     When active, the stack is checked for sufficient space before
            a subroutine call is executed.  This insures that space is
            available for local variables on the stack.

            When passive, no stack checks are made.
