Děkuji všem za snahu, rozšířilo mi to znalosti pointerů. Další
zkoumání však ukázalo, že souvislost s operátorem @ je spíše
nepřímá.<br>

První přiřazení je s počáteční bankou 1 a nefunguje. Druhé je
identické, ale s počáteční bankou 0 a již funguje. Při vynechání
operátoru @ je kód přiřazení mírně odlišný a funguje správně.<br>
