3.1.2 The Representation and Use of Procedures

This section introduces the basics of using and creating Scheme procedures. It discusses the representation of procedures as just another kind of Scheme value, and shows how procedure invocation expressions are constructed. We then explain how lambda is used to create new procedures, and conclude by presenting the various shorthand forms of define that can be used instead of writing an explicit lambda expression.

• Procedures as Values: Procedures are values like everything else.
• Simple Invocation: How to write a simple procedure invocation.
• Creating a Procedure: How to create your own procedures.
• Lambda Alternatives: Other ways of writing procedure definitions.
