How do I display font one character at a time?

Question

Right now the way I present my font is it all appears
instanenous. I don't know if this is even possible or not, but I
would like to find a way to have the font be displayed one
character at a time over the course of a variable amount of
seconds. For example, some of you might recognize this font
presentation from the game "Phoenix Wright" for the Nintendo DS:

for example.
That is the font effect I'm trying to capture - where the
font is presented in a character by character fashion. Now
obviously I could achieve this by putting a new letter on every
frame, but let's be realistic - that's not the logical way to do
it. Does anyone know the code/options involved in making this font
display stylization logically possible? Bonus points if you know
how to make the characters mouths move with the sychronized font
and then stop once the text stops =).

Answer 1

Place a dynamic textfield on your stage and label it myText.
In frame one place the following code,to increase the write
speed lower the value of 100 in the setinterval call:
myText.text="";
var dText="My text I want to display";
var dTmr=setInterval(ShowNextChar,100,0);
var cPos=0;
stop();
function ShowNextChar()
myText.text=myText.text+dText.substr(cPos,1);
cPos++;
if (cPos==dText.length) clearInterval(dTmr);
}
