将字节数组求和到 ax 寄存器

Sum a byte array to ax register

我有一个关于将一个字节数组求和到 ax 的问题,这是我的代码:

IDEAL
MODEL small
STACK 100h
DATASEG
; --------------------------
    arr db 6 dup (200)
; --------------------------
CODESEG
start:
    mov ax, @data
    mov ds, ax
; --------------------------
    xor ax, ax
    add ax, [arr]
    add ax, [arr + 1]
    add ax, [arr + 2]
    add ax, [arr + 3]
    add ax, [arr + 4]
    add ax, [arr + 5]
; --------------------------

exit:
    mov ax, 4c00h
    int 21h
END start


汇编器returns"Operand types do not match" 我是装配新手,我该如何克服呢? 谢谢

最终我这样做是为了解决我的问题:

IDEAL
MODEL small
STACK 100h
DATASEG
; --------------------------
    arr db 6 dup (200)
; --------------------------
CODESEG
start:
    mov ax, @data
    mov ds, ax
; --------------------------
    xor ax, ax
    xor bh, bh
    mov bl, [arr]
    add ax, bx
    mov bl, [arr + 1]
    add ax, bx
    mov bl, [arr + 2]
    add ax, bx
    mov bl, [arr + 3]
    add ax, bx
    mov bl, [arr + 4]
    add ax, bx
    mov bl, [arr + 5]
    add ax, bx
; --------------------------

exit:
    mov ax, 4c00h
    int 21h
END start
