1.13 For More Information

This chapter has covered a lot of ground! While you still have a lot to learn about assembly language programming, this chapter, combined with your knowledge of high-level languages, provides just enough information to let you start writing real assembly language programs.

Although this chapter has covered many different topics, the three primary topics of interest are the 80x86 CPU architecture, the syntax for simple HLA programs, and the HLA Standard Library. For additional topics on this subject, please consult the (unabridged) electronic version of this text, the HLA reference manual, and the HLA Standard Library manual. All three are available at http://www.artofasm.com/ and http://webster.cs.ucr.edu/.
