## 4.2. Names and Bindings

### 4.2.1. Name Binding

Names in AVAP refer to values and are introduced through name binding operations. The following constructs bind names:

* Formal parameters of functions.
* Function definitions.
* Assignment expressions.

Name binding is performed using the  `addVar(value, variable)`  function, which assigns the value to the specified variable. There are no class declarations or complex targets in AVAP. Only functions and direct assignments to variables are valid code blocks.
