这是一个基本的WIN32控制台模式 HelloWorld！ ASM程序，用MASM 615编译，运行在我的Win10，64位系统上。如果有任何修改（如果有），可以咨询作者的网站，使其编译VS 2019等。

启用指令并使用指向字符串的指针调用printf的示例masm代码。之所以指定旧库，是因为从Visual Studio 2015开始，printf和scanf现在在编译C源文件时内联，而汇编将需要使用旧库。如果程序同时包含C和汇编源文件，则不需要旧库。
可能需要自定义生成步骤。创建一个空的Windows控制台项目，添加程序集源文件，右键单击程序集源文件名，然后单击属性，将"从生成中排除"设置为"否"，然后设置自定义生成步骤参数：
对于调试版本：

command line: ml /c /Zi /Fo$(OutDir)\example.obj example.asm
output file:  $(OutDir)\example.obj

对于发布版本，不需要Zi：

command line: ml /c /Fo$(OutDir)\example.obj example.asm
output file:  $(OutDir)\example.obj

示例源代码：

.686p                   ;enable instructions
        .xmm                    ;enable instructions
        .model flat,c           ;use C naming convention (stdcall is default)

;       include C libraries
        includelib      msvcrtd
        includelib      oldnames
        includelib      legacy_stdio_definitions.lib    ;for scanf, printf, ...

        .data                   ;initialized data
pfstr   db      "Hello world!",0dh,0ah,0
        .data?                  ;uinitialized data
        .stack  4096            ;stack (optional, linker will default)

        .code                   ;code 
        extrn   printf:near
        public  main

main    proc

        push    offset pfstr
        call    printf
        add     sp,4 

        xor     eax,eax
        ret
main    endp

        end

对于64位版本，请使用ml64.exe而不是ml.exe。
