Concluzie: În această lucrare de laborator, unele aspecte ale limbajului de asamblare au fost consolidate și studiate în continuare. În procesul de realizare a lucrării, am studiat metodele și principiile de utilizare a comenzilor de manipulare a șirurilor. Codul scris a arătat simplitatea de a lucra cu comenzi de prelucrare a datelor cu minuscule.
