Environment Variables in WSH JS

[Dr John Stockton]

In javascript executed by Windows Scripting Host, one can input via
command-line parameters : File $95.js :-
x = WScript.Arguments
WScript.echo("Result:", x.length, typeof x, x[1], "OK")

Prompt>cscript //nologo $95.js 66 77 88
Result: 3 object 77 OK
The Arguments are 0-based.

Can one read/write Environment variables, and if so how? An answer for
VBscript could be useful, as well or in lieu.


Aside : <FAQENTRY> 2.11 : "over 5 years" is IMHO ambiguous. Suggest
"more than 5 years" or "for 5 years", whichever is meant.

Use the WshShell object to read the Environment property:

---
var ws, en, buf;

ws=WScript.CreateObject("WScript.Shell");
en=new Enumerator(ws.Environment)
buf=[];

for(;!en.atEnd();en.moveNext())
buf.push(en.item());

WScript.Echo(buf.join("\n"));
ws=null;
