Chapter 2 Program Development Flow

2.1Purpose of This Chapter

Programs can be developed with a compiler or an assembler.

Currently most program development is done with a compiler, but an assembler is where compact code generation or faster processing speed is required.

This chapter gives an overview of development with the assembler, and explains the flow of development through completion.
