This chapter presents a simple Pop-11 program worked out in some detail in order to give a feel for some of the structures in the language, including the definition of procedures, and the use of lists, conditionals and looping constructs.
Not all the details will be explained fully in this chapter. More general and complete explanations are given in later chapters. Ideally the reader should try out the example on a computer running Poplog, but, for readers with some programming experience, it should be intelligible without that. If some of the examples use a notation which is hard to understand, reading later chapters should make things clearer.
