- Impact of friendship:
- Access is granted to all components, regardless of the visibility section or the addition `READ-ONLY`.
- Friends of a class can create instances of the class without restrictions.
- Friendship is a one-way street, i. e. a class granting friendship to another class is not granded friendship the other way round. If class `a` grants friendship to class `b`, class `b` must also explicitly grant friendship to class `a` so that `a` can access the invisible components of c `b`.

- The name `itab` of the data object is determined at compile time and remains stable throughout the execution of the program.

- There are ABAP statements that include these dynamic aspects in the syntax. Assume you have simple program and a UI that includes an input field storing the input in a data object named `dbtab`.
