MASM錯誤：A2032錯誤指定的大小

Question

該程序應該將五個元素的數組與數組中每個元素的最小值和最大值進行比較。我不知道爲什麼當我比較陣列最大陣列和最小陣列我得到這個錯誤

1>......\Users\ross\Desktop\chapter6HW.asm(97): error A2032: invalid......\Users\ross\Desktop\chapter6HW.asm(99)r specified size

這是我的代碼。我已標記錯誤出現在** **。

arr1 BYTE 6,4,5,3,5 
arr2 BYTE 1,4,5,3,5 
arr3 BYTE 8,4,5,2,5 
arr4 BYTE 5,4,9,2,6

Answer 1

您無法將內存操作數與另一個內存操作數進行比較。你必須使用一個寄存器作爲中介：

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

---

另一個潛在的問題是，你的日常Display似乎沒有保留的esi原始值，這Validate_PIN依賴。
