var xhrObj;
..........
void function(){// emulate local block with anonimus function
    var context=...

    var arg2=...
    xhrObj.onreadystatechange = function(){
        HandlerFunction.call(context,arg1,arg2);
    }
}()//end of local block and run it

If You use array - be excelent with index in closure(last index most be geopardic actual for all handler).

aovc.js.html.ajax.sendRequest = function(url,params,callback,context,args)
{
...
var req= getHTTPRequest()
...
req.onreadystatechange=function() 
{
...
if (req.readyState == 4
{
		fcall.apply(context,ar);	
}
}

req.open(...);
req.setRequestHeader(...);
req.send(...);
}
