		c dw 100 dup(?)
		N db 8
data ends
code segment
	assume cs:code,ds:data
start:	mov ax,data
		mov ds,ax
		mov si,0
		xor di,di
		xor ax,ax
		xor bx,bx
		mov cl,N
		xor ch,ch
		
again:	mov ax,A[di]
        inc di
		mov bx,A[di]
		mov bl,bh
		xor bh,bh
		cmp ax,bx
		jl new
		cmp al,0

add code tags (the # button)

In what sense is it not working? Also, please use code tags (the # button) when posting code.

the code is not doing what it's have to do... he dosent work

[WingedPanther]

What does it do?

[petno]

its have to sort the numbers from 1,7,0bh,1,4,8,4,2 to 1,1,2,4,4,8,0bh

[WingedPanther]

So the problem is that it drops the 7?

Is there any particular reason why you're reading two numbers into AX but only one into BX? By the way, you set BX to zero initially and never touch BH again so you can change this:

mov bx,A[di]
mov bl,bh
xor bh,bh

to this:

mov bl, A[di]

What sorting algorithm are you trying to implement?

This urgency leads me to believe that this is a homework assignment, yes?
