Fnd_IO_MultiWindow

            Fnd_IO_MultiWindow ({enable}) ➔ Boolean

              Parameter               Type              Description
              form name               Text              True to enable multiple window mode (optional)
              Function result         Boolean           True if multiple window mode is enabled

            By default, Foundation displays input forms in a new process and window separate from the output form
            by opening a second window. This routine allows the developer to change this behavior so that input
            forms are displayed in the same process and window as the output form when double-clicking on a record
            in an output list.
            Pass True to enable multi-window mode, or pass False to disable multi-window mode.
              Fnd_IO_MultiWindow (True)

            This command will affect only the current process. It can be called from the
            Fnd_Hook_IO_DisplayTable hook.

            This routine can also be called without any parameters to determine the current setting:
              $multiWindowMode:=Fnd_IO_MultiWindow
