Return cscript output to batch [duplicate]

My batch script is performing an HTTP request by using CScript with Javascript syntax like in my example.

Using this approach (also seen here) and some help on escaping i tried the following:

@if (@This==@IsBatch) @then
@echo off
rem **** batch zone *********************************************************
    setlocal enableextensions EnableDelayedExpansion

    set OWNPATH="%~dpnx0"

    if not "%~11"=="" (
        FOR /F "usebackq tokens=*" %%r in (`cscript //E:JScript %OWNPATH%`) DO SET RESULT=%%r
        ECHO %RESULT%
    )

    exit /b

@end
// **** JScript zone *****************************************************
// Instantiate the needed component to make url queries
var http = WScript.CreateObject('Msxml2.XMLHTTP.6.0');

// perform request
var requestURL = "http://myserver/api";

// Make the request 
http.open("GET", requestUrl, false);
http.send();

WScript.Echo(http.ResponseText);

// All done. Exit
WScript.Quit(0);

Unfortunately i get a message that "ECHO is off." and not the string in %RESULT%.

The script is run on a Windows 2008 R2 server.
