Basic Hello World in Flash ActionScript 3.0

First of all I would like to mention there are 3 basic ways you can program a hello world program n actionscript 3.0
By instance names, creating TextFields in Frames, or creating TextFields in classes, and you can also manage the instance names in the classes as well.

Easiest Way to do this in my oppinion is through creating a dynamic textbox and giving the textbox an instance name. Then place in the actionscript in the frame.

The Way you do this is by grabbing the text field, and dragging it to the stage, then make the textbox dynamic and give it an instance name of what ever you would like. Such as "myTextBox1", without the quotes.

Then inside a Frame Post what you would like the textbox to say. The code is.

myTextBox1.text = "Hello World";

Or if you would like the TextBox to be a number you give it a int value or double value, others include uint, or float, or anything that pops up in the menu when you hit the colon button. However using float or uint are for pretty advanced users, int and double are basically so you can name what kind of number to place. int is a single digit number where it doesn't add points, such as 1,2,3,4,5,6,7,8....100, 20,000... and beyond, but is limitted to a very high number. double will create it so you can make it so the number has decimal points such as 1.01, 2.2, 3.33333... etc... however this is also limitted to a very high number.
