Function ViewObject Handle hoLevel Returns Handle
    Boolean bMdi
    Handle hoView
    
    Get Parent Of hoLevel To hoLevel
    If (hoLevel > Desktop) Begin
        Get Mdi_State Of hoLevel To bMdi
        If (Not (bMdi)) Begin
            Get ViewObject hoLevel To hoView
        End
        Else Begin
            Function_Return hoLevel
        End
    End
    
    Function_Return hoView
End_Function

Call this function with SELF as the parameter. For example as in:

Get ViewObject Self To hoView

If the dbView's MDI_State is set to False, the next level where the MDI_State is set to true will be returned.
