## 4.4. Exceptions

Exceptions in AVAP allow for the handling of errors or exceptional conditions. An exception is raised when an error is detected; it can be handled by the surrounding code block or by any code block that directly or indirectly invoked the block where the error occurred.

The AVAP interpreter raises an exception when it detects a runtime error. An AVAP program can also explicitly raise an exception using the  `raise`  statement. Exception handlers are specified with the  `try ... except`  statement.

Example of exception handling:

```javascript
try() 
    addVar(10 / 0, result)
except() 
    addResult("Cannot divide by zero.")
end()
```

In this example, if a division by zero occurs, a  `ZeroDivisionError`  exception is raised and handled by the  `except`  block.

This structure ensures that AVAP programs execute in a sequential and predictable manner, without advanced dynamic or deferred execution features, maintaining simplicity and clarity in name binding and import handling.
