Now we know a handful of Assembly Language instructions and can execute them linearly one after the other. We learned how to start and terminate a program. We built programs and debugged them.

In this chapter, we’ll make our programs more interesting by using conditional logic—if/then/else statements, from high-level languages. We will also introduce loops—for and while statements, from high-level languages. With these instructions in hand, we will have all the basics for coding program logic.

Note

We’ll start using small code snippets to demonstrate the concepts. These ...
