Hello avid game programmers...!

Uh... If you had read my last post, then you should know I'm struggling to make a simple RPG game...
Hope you can help me out in this prob.

How do you make those wording which appears as though they are being type?
If you're an avid RPG game player, then you should notice the way they present the text, coming out letters by letters.
Like mmm... Lufia, Breath of Fire, Tales of Destiny, Suikoden, Final Fantasy Series of course, etc

Well... I search for ways of doing so and I managed to do something similar with a timer
But I'm sure the experts out there have something else besides using the timer...
Please help me out...

Thanx a lot
