In this chapter, we look at the basic building blocks of a Red program—words and values. We discuss the different types available in Red, and what you can do with them. Some of the explanations may sound a bit dry at this moment, but because Red is quite different from other languages, you need to get a good understanding of its philosophy. Do try out the examples in the Red console! Things will also become more clear when we dive into code.
We will cover the following topics:
- Understanding words and values
- Some common datatypes
- Using blocks and parens
- Word bindings
- More about types
- Evaluating expressions and blocks
- The structure of a Red program
