El proyecto muestra:
* dos TableView, que representan el área de memoria reservada en el que insertar a uno más valores (tipo Byte) y el número de índice de cada celda de la memoria reservada. Cada celda del TableView representa una celda de la memoria reservada. Arriba es indicado, como ya dije, el número de índice por cada celda de memoria.
* un TextArea que muestra el consiguiente código que debería ser escrito para conseguir la cantidad elegida de memoria reservada y los valores que se quiere escribir.
Al inicio será solicitada la cantidad de memoria, de 1 a 16, que debe ser reservada.
Para insertar los valores de tipo Byte, hará falta hacer clic en una celda, escribir por lo tanto el valor de tipo Byte, de 0 a255, y en fin presioar la tecla "Enter" del teclado.
Es posible escribir de nuevo un valor en una celda, que ya haya sido valorizada.
