所以我从经验中知道，从 cmd.exe 运行有效程序并检查 %errorlevel% 将返回 0：

C:\>dir logo.bmp
 Volume in drive C has no label.
 Volume Serial Number is 5283-A7A2

 Directory of C:\

05/22/2008  12:43 PM         1,440,054 logo.bmp
               1 File(s)      1,440,054 bytes
               0 Dir(s)  71,723,995,136 bytes free

C:\>echo %errorlevel%
0

同样，尝试执行一个不存在的命令然后检查 %errorcode% 会给我一个 9009：

C:\>idontexist.exe
'idontexist.exe' is not recognized as an internal or external command,
operable program or batch file.

C:\>echo %errorlevel%
9009

多年来我一直在编写批处理脚本，它们一直以这种方式工作。但是，有人询问了有关该技术的兼容性（向前和向后）的问题，我找不到任何来自 Microsoft 的官方文档实际上将 9009 定义为找不到文件或程序时的错误级别。我最接近的是这个站点（http://msdn.microsoft.com/en-us/library/ms681381(v=vs.85).aspx），不幸的是，它将 9009 列为 DNS 错误。

有谁知道微软在哪里记录了这种行为？

Microsoft 有一个通用错误查找工具，可以为您翻译错误代码（包括 HRESULT，这很方便）。9009 的输出是：

# 4 matches found for "9009"

...所以您要查找的内容来自 cmdmsg.h。

它本身并不是真正的文档，但它至少是官方的。
