MSDN中介绍：
①Visual Studio 开发人员命令提示会自动设置环境变量，这些变量使你能够轻松使用 .NET Framework 工具。②开发人员命令提示将与 Visual Studio 一起安装。
从Visual Studio 2010 开始，你可看到多个命令提示，具体取决于你安装的 Visual Studio 和任何其他 SDK 的版本。例如，Visual Studio 的 64 位版本同时提供 32 位和 64 位命令提示。（大多数工具的 32 位和 64 位版本都相同；但少数工具针对具体的 32 位和 64 位环境做了一些改变。）
对于 Windows 7 中的 Visual Studio（任何版本）
- 选择“开始”，然后选择“所有程序”、“Microsoft Visual Studio”、“Visual Studio Tools”和“Visual Studio 命令提示”。
我们右键“Visual Studio 命令提示”->属性可看到执行“Visual Studio 命令提示”实际上是运行了一个.bat文件 加上了不同的对应参数：
“Virtual Studio命令提示（2010）"对应于：
%comspec% /k ""D:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" x86
“Virtual Studio x64 兼容工具命令提示”对应于：
%comspec% /k ""D:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" x86_amd64
“Virtual Studio Itanium 兼容工具命令提示”对应于：
%comspec% /k ""D:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" x86_ia64
我们打开""D:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" 文件：
1 @echo off 2 if "%1" == "" goto x86 3 if not "%2" == "" goto usage 4 5 if /i %1 == x86 goto x86 6 if /i %1 == amd64 goto amd64 7 if /i %1 == x64 goto amd64 8 if /i %1 == ia64 goto ia64 9 if /i %1 == x86_amd64 goto x86_amd64 10 if /i %1 == x86_ia64 goto x86_ia64 11 goto usage 12 13 :x86 14 if not exist "%~dp0bin\vcvars32.bat" goto missing 15 call "%~dp0bin\vcvars32.bat" 16 goto :eof 17 18 :amd64 19 if not exist "%~dp0bin\amd64\vcvars64.bat" goto missing 20 call "%~dp0bin\amd64\vcvars64.bat" 21 goto :eof 22 23 :ia64 24 if not exist "%~dp0bin\ia64\vcvars64.bat" goto missing 25 call "%~dp0bin\ia64\vcvars64.bat" 26 goto :eof 27 28 :x86_amd64 29 if not exist "%~dp0bin\x86_amd64\vcvarsx86_amd64.bat" goto missing 30 call "%~dp0bin\x86_amd64\vcvarsx86_amd64.bat" 31 goto :eof 32 33 :x86_ia64 34 if not exist "%~dp0bin\x86_ia64\vcvarsx86_ia64.bat" goto missing 35 call "%~dp0bin\x86_ia64\vcvarsx86_ia64.bat" 36 goto :eof 37 38 :usage 39 echo Error in script usage. The correct usage is: 40 echo %0 [option] 41 echo where [option] is: x86 ^| ia64 ^| amd64 ^| x86_amd64 ^| x86_ia64 42 echo: 43 echo For example: 44 echo %0 x86_ia64 45 goto :eof 46 47 :missing 48 echo The specified configuration type is missing. The tools for the 49 echo configuration might not be installed. 50 goto :eof
发现针对不同的参数，vcvarsall.bat打开了不同的文件(比如， x86参数是调用了"%~dp0bin\vcvars32.bat“①文件；
我们打开"%~dp0bin\vcvars32.bat“①文件进行查看：

vcvars32.bat
一堆@set PATH 、@set LIBPATH之类的..看的有点晕....
备注：
①"%~dp0": 0念 零 ，代表你的批处理本身。 d p是FOR 命令的扩展。
%~f0 将 %I 扩展到一个完全合格的路径名
%~d0 仅将 %I 扩展到一个驱动器号
%~p0 仅将 %I 扩展到一个路径
%~n0 仅将 %I 扩展到一个文件名
%~x0 仅将 %I 扩展到一个文件扩展名
%~s0 扩展的路径只含有短名
%~a0 将 %I 扩展到文件的文件属性
%~t0 将 %I 扩展到文件的日期/时间
%~z0 将 %I 扩展到文件的大小
比如：d:\123\a.bat；
%~p0是d:\
%~pd0就是d:\123
%0就是 d:\123\a.bat
