A user interface in which the user gives an example of the desired operation and the system generalizes to construct a general-purpose procedure is discussed. The user sees the results of the program execution and the data the program is operating on, but the program itself is not shown. The program is specified by demonstrating the operations that should be performed using example data. These systems are called programming-by-example or demonstrational interfaces. An overview of this idea and a survey of such systems are presented.>
