    ASSUME CS:CODES,DS:DATAS,SS:STACKS
START:
    MOV AX,DATAS
    MOV DS,AX
   xor al,al
   xor bx,bx
   mov ax,b+5; MOV     AX,[0001]
   ; mov ax,b[ax] 不对因为ax不能作为间址寄存器
   mov ax,[bx][si+2] ; MOV     AX,[BX+SI+02]
   MOV     AX,[BX+SI+02]
   MOV     AX,[bx+02]
   mov ax,seg DATAS ; MOV     AX,13E6 伪指令汇编期间就完成
   inc b   ; INC     WORD PTR [0000]
   ;**********************************
     mov bx,2h
   ;push bx
; ret
   ;jmp bx ;可以任意改地址使下面的执行不了如果是向上跳效果基本一样
   ; ret把压入的bx取出给ip 和jmp bx ,call bx 一样

; call bx
