How to use "options.printOptions() cmd in DSS ?

I'm using CCS 5.5.0 and my target is F28335 and I'm trying to set few configuration settings using DSS scripts.

I tried the following command in the scripting console after connecting to the target....

activeDS.options.printOptions(".*");

but it wasn't printing anything. I ran the below JavaScript. Still nothing.

function load_code()
{
	print("Hello");
	dssScriptEnv = ScriptingEnvironment.instance();	 

	debugServer = dssScriptEnv.getServer("DebugServer.1");
	debugServer.setConfig("ezDSP28335.ccxml"); 
	debugSession = debugServer.openSession("*", "*"); 
	
	var opt;
	opt= debugSession.options.printOptions(".*");
	print(opt);
	debugSession.flash.options.printOptions(".*");

}  

Still nothing on the console window. Am I missing something? How to get the list of options related to the debugsession or the flash settings?
