Eval functionality for AS3?

Question

I have searched through the forums and the web on this topic
but can't seem to find a solution that works for my situation. I
used to use the eval function in AS2 to access methods and
properties of dynamically named variables but it seems to be much
different in AS3.
A simple example :
var number_of_records:int=10;
var i:int = 1;
do {
// the next line is what i want to emulate in AS3
eval(mydynamicvariable_+i)._alpha = 0
i+=1;
}while (i<=number_of_records);
Below is a different example and actually pertains more to to
my question than the above example.
I am get variables from a text file. Got that part working.
My variables are going to be put into an array and then used in a
dataprovider for the datagrid component. Got the last part working
too. Just having difficulty accessing my variables dynamically and
then putting them in an array. First I just want to trace my
variables and that is what i am having difficulty doing. I can
trace them with hardcoding them but not dynamically.
//////////////My data.txt file example is:
number_of_records= 10
&record_1=variable 1
&first_name_1=this someones name 1
&last_name_1=this is somones last name 1
&details_1=just some text 1
&record_2=variable 2
&first_name_2=this someones name 2
&last_name_2=this is somones last name 2
&details_2=just some text 2
//////////////.. and so on to 10 for this example..
//////////////My data.txt file is loaded with the following
code into flash CS3 using AS3
var myURLLoader:URLLoader= new URLLoader();
var myURLRequest:URLRequest = new URLRequest("data.txt");
myURLLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
myURLLoader.load(myURLRequest);
myURLLoader.addEventListener(Event.COMPLETE, dataOK);
function dataOK(myevent1:Event):void{
var
number_of_records:int=myURLLoader.data.number_of_records;
trace("data is loaded");
trace("number_of_records="+number_of_records);
var i:int = 1;
do {
//////////////THE CODE ON THE NEXT FEW LINES IS MY QUESTION
//////////////THE SECOND HALF IS HOW I WOULD WRITE IT IN AS2
TO DYNAMICALLY ACCESS THE VARIABLES
trace(
"record_"+i.toString()+"="+eval("myURLLoader.data.record_"+i));
trace(
"first_name_"+i.toString()+"="+eval("myURLLoader.data.first_name_"+i));
trace(
"last_name_"+i.toString()+"="+eval("myURLLoader.data.last_name_"+i));
trace(
"details_"+i.toString()+"="+eval("myURLLoader.data.details_"+i));
i+=1;
}while (i<=number_of_records);
How do i trace those variables with a loop using AS3? I can
then figure out how to put it into the array and to get the info
into the datagrid. Hope that I have provided enough information
about my problem and hope that it is a simple solution.
Please help and thanks!

Andrei1 your awesome. Thanks dude! That's exactly what I was
looking for. I actually did something similar but my syntax was not
correct. I tried :
trace(
"record_"+i.toString()+"="+myURLLoader.data.["record_"+i])
///with a period before the []
obviously wrong. Thanks again.
trace(
"record_"+i.toString()+"="+myURLLoader.data["record_"+i])
///without the period was correct.
