Question

我从来没有发布到堆栈溢出，我不确定我是否正确发布。

我是使用MASM的新手，我正在开发一个项目，在Windows8操作系统上使用VisualStudio 2012创建Hex游戏。我们计划用C ++添加一个UI接口，所以我们调用过程，但不确定为什么每次调用一个过程时我都会得到这个未定义的错误符号。

另外，当在proc（即TotalSearch）中访问我们的邻接数组时，我们是否传入一个指向邻接数组本身的指针或传递我们声明的指针？

例如，TotalSearch Proc代码标题现在是：

TotalSearch PROC PUBLIC, AP:PTR DWORD, AI:SDWORD

其中AP是adjptr，它是邻接数组的指针所以它是使用：

调用的

INVOKE TotalSearch, adjptr, arrayindex

是否应该以这种方式调用，所以我们传入的是数组的偏移而不是实际的指针本身？如果是这样，如果这些是传入的参数，那么指针是否需要？：

这是数组：

adjacency SDWORD 6 DUP (0)

这应该是电话吗？

INVOKE TotalSearch, adjacency, arrayindex

这些是我每次调用过程时都会遇到的错误：

1>------ Build started: Project: ASM_Project, Configuration: Debug Win32 ------

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

这是我们的代码。有些行被注释掉，因为我尝试了不同的东西来构建它，但没有一行是成功的。另外，你可以使用声明的常量作为proc中的参数（即redStone）吗？我正在尝试，但不知道我能否，因为它不会建立。

Answer 1

问题是您从未定义过程的入口点。您需要添加带有过程名称的标签以标识入口点。例如：

        :
ShowBoardColors PROC PUBLIC, AI:SDWORD, BS:SDWORD

; entry point at the beginning of the procedure
ShowBoardColors:

; set array index to 0 and initialize two loop counters in eBx and eCx

mov eax,AI
MOV eax, 0
        :

在程序中调用程序给出“错误A2006：未定义的符号”
