This tutorial is for those who are just getting started with ComputerCraft.
Creating the Program
Creating a Hello World program is a simple task and does not require much knowledge in Lua or ComputerCraft. The first step is to create the program so we can edit it. Access your computer and type:
edit helloworld
You will now have a blank program that you can edit.
We can make the computer print "Hello World!" in two different ways.
To print it letter by letter, type:
textutils.slowPrint("Hello World!")
To just print it, type:
print("Hello World!")
Now, press CTRL and make sure Save is selected, then press ENTER or RETURN. The program is now completed and saved, so let's exit edit mode. Press CTRL and select Exit by using the arrow keys. Once selected press ENTER or RETURN.
To test it, type:
helloworld
Simple isn't it?
