Abstract
After the rules of syntax and semantics, the three most basic components of all Lisp programs are functions, variables and macros. You used all three while building the database in Chapter 3, but I glossed over a lot of the details of how they work and how to best use them. I’ll devote the next few chapters to these three topics, starting with functions, which—like their counterparts in other languages—provide the basic mechanism for abstracting, well, functionality.
