【问题描述】：

我修复了错误，但现在有人可以建议一种方法让CountNearMatches 计算两个数组中有多少近匹配项。我使用 diff 变量作为最大允许差异。

这是我目前所拥有的：

    INCLUDE Irvine32.inc

CountNearMatches PROTO,           ; procedure prototype
    arr1:PTR SDWORD,
    arr2:PTR SDWORD,
    diff3:DWORD

.data

arraySyze DWORD 6
    diff DWORD 3
    index DWORD  0           ;var to use as the first index

    Array1  SDWORD  15, 9, 11, 13, 19, 6
    Array2  SDWORD  14, 5, 3, 12, 1, 4  

    text1 BYTE "************* ASM *****************", 0
    text2 BYTE "*** Counting Nearly Matching Elements ***", 0
    text3 BYTE "the arrays are:...", 0
    text4 BYTE "Nearly Mathces were: ",0

.code
main PROC

    mov edx, offset text1       ;hands the address of the firs char of text1
    call WriteString            ;prints out text1
    call Crlf
    call Crlf

    mov edx, offset text2       ; hands the address of the firs char of text2
    call WriteString            ; prints out text2
    call Crlf
    call Crlf

    mov edx, offset text3       ;hands the address of the firs char of text3
    call WriteString            ;prints out text3
    call Crlf

    mov  esi,OFFSET Array1      ; puts the offset of array in esi
    mov  ecx,arraySyze          ;6
    mov  ebx,TYPE Array1                            
    call DumpMem
    call Crlf

    mov  esi,OFFSET Array2      ; puts the offset of array in esi
    mov  ecx,arraySyze          ;  6
    mov  ebx,TYPE Array1                            
    call DumpMem

    mov eax,0
swapLoop:
    mov ebx, index              ;moves index1 to ebx


    ;here i use the registers to add 8 in to the stack addresses
    INVOKE CountNearMatches, ADDR[Array1 + ebx], ADDR[Array2 + ebx], diff

    add ebx, 4                  ;adding 4 to ebx
    mov index, ebx              ;putting ebx back in to index1

    loop swapLoop

    call Crlf

    mov edx, offset text4       ;hands the address of the firs char of text4
    call WriteString            ;prints out text4



    call WriteInt

    call Crlf
    call Crlf


    call WaitMsg                ; Press any key to contineu...
    exit
main ENDP

    diff3:DWORD                         ;gets the diff from the stack

【问题讨论】：

我假设它在特定行上给你那个错误？？？
您收到的完整错误消息是什么？您使用什么命令来组装此文件？
感谢您的回答..我是组装新手...我使用 VS 组装文件，它在文件底部的原型定义的第一行给出了错误- -- CountNearMatches PROC 使用 eax esi edi，
我得到的错误是第 71 行的“错误 A2071：初始化器幅度对于指定大小而言太大”
我无法重现该错误。至少 PROTO 声明 CountNearMatches 和 PROC 标头不匹配。

我想通了.. 现在它实际上计算了所有接近的匹配项，不确定这是否是最好的方法，但它有效。这是我想出的

    INCLUDE Irvine32.inc

CountNearMatches PROTO,                                  ; procedure prototype

       count DWORD 0
        Array1  SDWORD  15, 9, 11, 13, 19, 6
        Array2  SDWORD  14, 5, 3, 12, 1, 4     

        text1 BYTE "************* ASM *****************", 0
