Chapter 16. Parsing an Imperative Language
This chapter shows how to create imperative languages, which are also called programming or scripting languages. An imperative language lets a user create a collection of commands (the program or script) that, within some context, direct the computer's actions. A parser for an imperative language translates a user's program into an executable composition of commands.
To provide a running example of how to construct an imperative language, this chapter uses Sling, a programming language created for this book. Sling allows a user to compose mathematical functions and to request plots of these functions. A Sling environment accepts Sling programs and displays a user's plots.
