How do you pause between text in this code? - actionscript-3

Question

I'm trying to put a pause between "Long ago," and what comes after that but I'm having trouble trying to do it. How could I make it work? I've attempted to use a timer but I'm not very good at doing that which made it hard to implement it.
Here is my code:
var snd: textStory = new textStory();
var snd2: soundStory = new soundStory();
var myString: String = "Long ago, two races\nruled over Earth:\nHUMANS and MONSTERS.";
var myArray: Array = myString.split("");
snd2.play();
addEventListener(Event.ENTER_FRAME, frameLooper);
function frameLooper(event: Event): void {
if (myArray.length > 0) {
if (n == 1) {
tf.appendText(myArray.shift());
n = 0;
snd.play();
} else {
n++;
}
} else {
removeEventListener(Event.ENTER_FRAME, frameLooper);
}
}

Something like that, I think. It is a data-driven solution where you prepare a proper data input so that your main loop (ENTER_FRAME handler in your case) won't have to think too much and just process one data entry at once.
var E:Array = [""];
// It is considered a good tone to name classes
// starting with uppercase: TextStory, SoundStory.
var snd: textStory = new textStory();
var snd2: soundStory = new soundStory();
var laString:String = "Long ago";
var myString:String = ", two races\nruled over Earth:\nHUMANS and MONSTERS.";
var myArray:Array = new Array;
// Here we form an Array that starts with "Long ago"
// then 20 empty entries to skip, then the rest.
myArray = myArray.concat(tocharArray(laString));
myArray = myArray.concat(emptySpaces(20));
myArray = myArray.concat(tocharArray(myString));
snd2.play();
addEventListener(Event.ENTER_FRAME, frameLooper);
function frameLooper(event: Event): void
{
if (myArray.length < 1)
{
removeEventListener(Event.ENTER_FRAME, frameLooper);
return;
}
var aChar:String = myArray.shift();
// Just skip a frame if there's an empty character.
if (aChar == "")
{
return;
}
tf.appendText(aChar);
// Make no typing sound on space characters... I guess?
if (aChar != " ")
{
snd.play();
}
}
// Returns an Array ["", "", "", ... , ""] of the given length.
function emptySpaces(length:int):Array
{
// This doubles E as many times as needed
// to allow us to make a slice long enough.
while (E.length < length)
{
E = E.concat(E);
}
// Returns a portion of E of the given length.
return E.slice(0, length);
}
// Converts the given String into an Array
// of characters and empty "" entries.
function tocharArray(value:String):Array
{
var result:Array = new Array;
for (var i:int = 0; i < value.length; i++)
{
// You can put more or less "" here to make the
// typing loop skip more than a single
// frame after typing a character.
result.push(value.charAt(i), "", "");
}
return result;
}
