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

   Syntax:              GetWindowWord( <hWnd>, <nIndex> )  --> <nValue>


   Parameters:

   <hWnd>               The handle of the window whose Index associated
                        word ( two bytes ) value is to be retrieved.

   <nIndex>             Specifies the zero-based index order of the value
                        to be retrieved.

                        #define GWW_HINSTANCE       (-6)
                        #define GWW_HWNDPARENT      (-8)
                        #define GWW_ID              (-12)

                        GWW_HINSTANCE   Specifies the instance handle of the
                                        module that owns the window.
                        GWW_HWNDPARENT  Specifies the handle of the parent
                                        window, if any. The SetParent function
                                        changes the parent window of a child
                                        window. An application should not call
                                        the SetWindowWord function to change
                                        the parent of a child window.
                        GWW_ID          Specifies the identifier of the child
                                        window.

   Returns:

   <nValue>             The returned value specifies information about the
                        given value.
