# The basics

In this first part of the tutorial we will create a simple "Hello World" program to run on the Commodore 64. This will cover:

- How to make programs run on a Commodore 64

- Writing simple code with labels

- Numeric and string data

- Invoking the assembler

# A note on numeric notation

Throughout these tutorials, I will be using a lot of both decimal and hexadecimal notation. Hex numbers will have a dollar sign in front of them. Thus, 100 = $64, and $100 = 256.
