我們可以列出與 SYSTEM 相關的重要環境變數：

原始檔（envVarSystem01.js）：

（灰色區域按兩下即可拷貝）

// 列出重要的環境變數

wshShell = WScript.CreateObject("WScript.Shell");
wshSysEnv = wshShell.Environment("SYSTEM");
WScript.Echo("重要的環境變數：");
name="windir"; WScript.Echo(name+" = "+wshSysEnv(name));
name="path"; WScript.Echo(name+" = "+wshSysEnv(name));
name="NUMBER_OF_PROCESSORS"; WScript.Echo(name+" = "+wshSysEnv(name));
name="OS"; WScript.Echo(name+" = "+wshSysEnv(name));
name="PROCESSOR_ARCHITECTURE"; WScript.Echo(name+" = "+wshSysEnv(name));
name="temp"; WScript.Echo(name+" = "+wshSysEnv(name));

典型顯示結果如下：

重要的環境變數： windir = %SystemRoot% path = %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;c:\matlab6p 5\bin\win32;C:\Program Files\Microsoft SQL Server\90\Tools\binn\ NUMBER_OF_PROCESSORS = 1 OS = Windows_NT PROCESSOR_ARCHITECTURE = x86 temp = %SystemRoot%\TEMP 我們可以列出與 SYSTEM 相關的全部環境變數：

原始檔（envVarSystem02.js）：

（灰色區域按兩下即可拷貝）

// 所有的 SYSTEM 環境變數列表

shell = WScript.CreateObject("WScript.Shell");
envObj = shell.Environment("SYSTEM");
WScript.Echo("所有的 SYSTEM 環境變數列表：");
WScript.Echo("No. of env. variables = "+envObj.length);
var Enum=new Enumerator(envObj) 
for (Enum.moveFirst(); !Enum.atEnd(); Enum.moveNext())
	WScript.Echo(Enum.item());

典型顯示結果如下：

原始檔（envVarProcess01.js）：

（灰色區域按兩下即可拷貝）

// 所有的 PROCESS 環境變數列表

shell = WScript.CreateObject("WScript.Shell");
envObj = shell.Environment("PROCESS");
WScript.Echo("所有的 PROCESS 環境變數列表：");
WScript.Echo("No. of env. variables = "+envObj.length);
var Enum=new Enumerator(envObj) 
for (Enum.moveFirst(); !Enum.atEnd(); Enum.moveNext())
	WScript.Echo(Enum.item());

典型顯示結果如下：
