我有一个河内的assembly32代码，但我无法编译它，我得到错误： hanoi.asm（9）：错误A2070：无效的指令操作数我使用MASM32。

完整代码：

.MODEL  FLAT

.CODE

        MOV   EBP, ESP
        SUB   ESP, 4
        CMP   [EBP+8], 1   ;ERROR
        JNE   L1
        MOV   EAX, [EBP+16]
        PUSH  EAX
        MOV   EAX, [EBP+12]
        PUSH  EAX
        PUSH  OFFSET FLAT:format;
        CALL  _printf
        ADD   ESP, 12

        PUSH  EAX
        MOV   EAX, [EBP+12]
        PUSH  EAX
        PUSH   1
        CALL   _towers

你能帮助我吗，我该怎么做才能做到这一点？

你的代码对我不起作用，我运行它但算法有问题，它从未找到解决方案。

所以，这是另一个真正有用的河内塔解决方案。它是用EMU8086（MASM Intel语法）制作的，你只需复制粘贴并运行：

.model small
.stack 300H
.data
x dw 3
text db "Move from peg "
d1 db ?
text2 db " to peg "
d2 db ?
newline db 0AH, 0DH, '$'

.code
main proc

    mov ax, @data
    mov ds, ax

    mov ax, 1
    push ax
    mov ax, 3
    push ax
    mov ax, 2
    push ax
    mov ax, x
    push ax
    call solve

    mov ax, 4C00H
    int 21h


main endp

solve proc
   push bp
   mov bp, sp
   cmp word ptr ss:[bp+4], 0
   je down

   push word ptr ss:[bp+0AH]
   push word ptr ss:[bp+6]
   push word ptr ss:[bp+8]
   mov ax, word ptr ss:[bp+4]
   dec ax
   push ax
   call solve

   push word ptr ss:[bp+0AH]
   push word ptr ss:[bp+08]
   call print

   push word ptr ss:[bp+06H]
   push word ptr ss:[bp+8]
   push word ptr ss:[bp+0AH]
   mov ax, word ptr ss:[bp+4]
   dec ax
   push ax
   call solve

   pop bp
   ret 8
down:
   pop bp
   ret 8

solve endp

print proc
   push bp
   mov bp, sp
   mov d1, '0'
   mov al, byte ptr ss:[bp+06]
   add d1, al
   mov d2, '0'
   mov al, byte ptr ss:[bp+4]
   add d2, al
   lea dx, text
   mov ah, 09
   int 21h
   pop bp
   ret 4

print endp
end

还记得我对初始化数据的看法吗？好吧，这个有它！也许这就是它起作用的原因。
