Q8: find even number from 1000 to 2000

org 100h

.data

dt1 dw 500 dup(0)

.code 

 mov ax,@data

 mov ds,ax

 mov si, offset dt1

 mov bx,1000

 mov cx,500

 label:

 mov [si],bx

 add bx,0002

 inc si

 inc si

 loop label

hlt

note: see in memory in two byte CE and 06 equal 1998 , so it down 1996 see cc,07

another way for find even number from 1000 to 1500:

org 100h

.data

dt1 db 250 dup(0)

.code

mov ax,@data

mov ds,ax

mov si,offset dt1

mov cx,1000

mov bx,02

new:

    mov [si],cx

    add cx,bx

    add si,bx

    cmp cx,1500

    jle new
