Jscript and environment variables

Jscipt From Microsoft ( http://en.wikipedia.org/wiki/Jscript)
And I want it to get a Environmental variable Like the path or username.
Open a cmmand prompt and type Set.
One of those variables.

Thanks

insted of ..

var WshShell = WScript.CreateObject("WScript.Shell");

try

var wshShell = new ActiveXObject("WScript.Shell");

JScript .NET is what Microsoft calls it and it is used in InfoPath (part of MS office)
So there is no browser..

Then I get this
Expected ';'
File:script.js
Line:52
Set oShell = CreateObject("WScript.Shell");

If I fully Trust the Form/code with the 2 different options I get

var wshShell = new ActiveXObject("WScript.Shell");
var wshEnv = WSHShell.Environment("Volatile");
var test = wshEnv("Prompt");

'WSHShell' is undefined in line 2

OR

var WshShell = WScript.CreateObject("WScript.Shell");
var wshEnv = WSHShell.Environment("Volatile");
var test = wshEnv("Prompt");

'WScript' is undefinded in Line 1

THanks

variable name is case-sensitive..

var wshShell = new ActiveXObject("WScript.Shell");
var wshEnv = wshShell.Environment("Volatile");
var test = wshEnv("Prompt");

Thanks This all works now.
So in My login script I search AD and pull out Information and write it to Environmant Variables.
Then in Infopath I can grab them.

But the InfoPath form does have to be fully trusted and Signed.

Here is the Final CODE: THANKS

var wshShell = new ActiveXObject("WScript.Shell");
var wshEnv = wshShell.Environment("PROCESS");
XDocument.DOM.selectSingleNode("/my:myFields/my:Username").text = wshEnv("USERNAME");
XDocument.DOM.selectSingleNode("/my:myFields/my:Email").text = wshEnv("EMAIL");
XDocument.DOM.selectSingleNode("/my:myFields/my:Last_Name").text = wshEnv("LASTNAME");
XDocument.DOM.selectSingleNode("/my:myFields/my:First_Name").text = wshEnv("FIRSTNAME");
