7.2 Low Level Control Structures

Until now, most of the control structures you've seen and have used in your programs are similar to the control structures found in high level languages like Pascal, C++, and Ada. While these control structures make learning assembly language easy they are not true assembly language statements. Instead, the HLA compiler translates these control structures into a sequence of "pure" machine instructions that achieve the same result as the high level control structures. This text uses the high level control structures to allow you to learn assembly language without having to learn everything all at once. Now, however, it's time to put aside these high level control structures and learn how to write your programs in real assembly language, using low level control structures.
