Planning the Program
Part of the Fundamentals section of Coddy's Assembly journey — lesson 43 of 45.
You have learned all the pieces: data definition, MOV instructions, exit syscall, and write syscall. Now it is time to put everything together to write a complete "Hello, World!" program from scratch.
Before writing any code, you need a plan.
The four steps to print "Hello, World!":
| Step | What to do | Which chapter taught this |
|---|---|---|
| 1 | Create the .data section with the string | Chapter 3 |
| 2 | Calculate the string length automatically | Chapter 3 |
| 3 | Set up and call the write syscall | Chapter 5 |
| 4 | Set up and call the exit syscall | Chapter 4 |
In the next lessons, you will write each part step by step, then put them all together.
