MASM 错误：A2032 错误指定大小

Question

这个程序应该将一个包含五个元素的数组与数组中每个元素的最小值和最大值进行比较。我不确定为什么当我将数组与最大数组和最小数组进行比较时会出现此错误

1>......\Users\ross\Desktop\chapter6HW.asm(97): 错误 A2032: 无效......\Users\ross\Desktop\chapter6HW.asm(99)r 指定大小

这是我的代码。我已经用** ** 标记了错误的位置。

str1 BYTE "Invalid",0

Answer 1

你不能像这样将一个内存操作数与另一个内存操作数进行比较。您必须使用寄存器作为中介：

mov al,[esi]
cmp al,minArr[edi]
jb L2
cmp al,maxArr[edi]

---

另一个潜在问题是您的Display 例程似乎没有保留esi 的原始值，Validate_PIN 依赖于该值。
