请教VC的命令行cl命令如何用

请问VC的命令行cl命令怎么用？
我建了一个hello.c文件，在命令行中输入cl hello.c，提示cl is not recognize as an internal or external command,怎么回事？

先执行一下VCVARS32.BAT，请根据你安装的路径修改

VBScript code

@echo offremrem Root of Visual Developer Studio Common files.set VSCommonDir=C:\PROGRA~1\MICROS~4\Commonremrem Root of Visual Developer Studio installed files.remset MSDevDir=C:\PROGRA~1\MICROS~4\Common\msdev98remrem Root of Visual C++ installed files.remset MSVCDir=C:\PROGRA~1\MICROS~4\VC98remrem VcOsDir is used to help create either a Windows 95 or Windows NT specific path.remset VcOsDir=WIN95if "%OS%" == "Windows_NT" set VcOsDir=WINNTremecho Setting environment for using Microsoft Visual C++ tools.remif "%OS%" == "Windows_NT" set PATH=%MSDevDir%\BIN;%MSVCDir%\BIN;%VSCommonDir%\TOOLS\%VcOsDir%;%VSCommonDir%\TOOLS;%PATH%if "%OS%" == "" set PATH="%MSDevDir%\BIN";"%MSVCDir%\BIN";"%VSCommonDir%\TOOLS\%VcOsDir%";"%VSCommonDir%\TOOLS";"%windir%\SYSTEM";"%PATH%"set INCLUDE=%MSVCDir%\ATL\INCLUDE;%MSVCDir%\INCLUDE;%MSVCDir%\MFC\INCLUDE;%INCLUDE%set LIB=%MSVCDir%\LIB;%MSVCDir%\MFC\LIB;%LIB%set VcOsDir=set MSVCDir=set MSDevDir=set VSCommonDir=

需要注册一些环境变量
你google搜索一下, vc命令行 之类的关键字应该就可以找到答案
[解决办法]
对于LZ的要求，其实只要把cl.exe的路径放入系统的path即可。我的vim就是这么干的
[解决办法]
要设置环境变量,在环境变量中设置cl命令所在文件夹为查找路径,才能在任意目录下执行cl命令.
