Afisarea unei variabile de tip dw

[skullbox]

Salut la toti
cum  se poate afisa la monitor  valoarea unei  variabile de tip dw?

daca se poate prin nishte exemple de lamurit

[emi]

dar cum afisezi o variabila de tip word, sau byte ?
vrei in hexa, sau transformat in baza 10 ?

Nu cred ca ar trebui sa precizez, dar totusi, daca nu e evident, codul e pentru procesoare 8086, sau 286.
Pentru cod 386, ar trebui rescris pentru eficienta, nu ca nu ar functiona.
