Assembler, find out if there are two zeros in the pool running around. Message of words

We need to know if there are two zeros going in a row. Why turns the unit out if there's no zero in the body, how do you fix it?

[guilherme]

It's nothing code

NN:
    mov ax,1
    loop beg

You always do.

at [bx] or [bx + 2] == 0 You're jumping right there, and if the condition isn't met, a couple of times. inc bx Come on.

I'd rather do that.

    mov  ax, [bx]
    or  ax, [bx+2]
    jnz  NN
    mov dx,1
NN:
    inc bx
    inc bx
    loop beg
quit:

If I'm right,

P. S.

That you're a double zero flag. ax write, which is further used for other purposes mov ax, 4c00h ?
