   You can redirect the output of CSCRIPT using `for /f` with the CSCRIPT   
   command line and parse its output. Or the output can be redirected into a   
   file first if a result file is needed.   
      
   e.g. the JS file part (test.js):   
      
   WScript.echo("Result from cscript");   
      
   The batch file part, with direct parsing, e.g.   
      
   @echo off   
   setlocal   
   set res=   
   for /f "delims=" %%A in ('cscript.exe //nologo test.js') do set "res=%%A"   
   echo result=%res%
