* First, select the number $(1,\ 2, \text{...} \ )$ of the task to be processed. The number "$0$" corresponds to a "Reset": Same setting as at program start.
* A task description is displayed. The parameter values are adjusted. Solution after pressing "Show Solution".
* Source symbols are denoted by uppercase letters (binary: $\rm A$, $\rm B$), sink symbols by lowercase letters ($\rm a$, $\rm b$). Error-free transmission: $\rm A \rightarrow a$.
* For all entropy values, the unit "bit/use" would have to be added.
