              position setting                    Longint   Window position (optional)
              Function result                     Number    The position setting for the next window

            Allows the developer to set the window position for the upcoming dialog or window. The following
            positions are available using these constants:
              Value              Foundation Constant              Description
              0                  Default                          Centered on screen
              1                  Fnd_Wnd_CenterOnScreen           Centered on screen
              2                  Fnd_Wnd_CenterOnWindow           Centered over front most window
              3                  Fnd_Wnd_MacOSXSheet              Sheet if possible, or centered over front most window
              4                  Fnd_Wnd_Stacked                  Stacked with other stacked windows
              5                  Fnd_Wnd_StackOnWindow            Stacked over the front most window

            The Fnd_Wnd_MacOSXSheet position will use the sheet type window when using 4D 2004 or later
            on Mac OS X. It will also be used for alert and confirm dialogs displayed by the Dialog component, if the
            ToolboxPack plugin is installed. Otherwise, the window will be centered over the front most window.
            This command can be called before using many Foundation routines that take advantage of the Windows
            component. For example:
              Fnd_Wnd_Position (Fnd_Wnd_CenterOnWindow )
              Fnd_Dlg_Alert ("A value in the Company field is required.")
