To fill the table contents, it is necessary to pass through the first key attribute in the scheme description. We can enter (Insert), correct (Update) or delete (Delete) records separately. For navigation, the <<, <, go, >, >> references are used. It is possible to pass to the necessary record directly through the "go". In so doing, it is enough to enter only corresponding number, if key field has type Number, or first symbols, if key field has the Char type.
