## 5.3. Advanced Example

Consider the following example where multiple files are imported:

```javascript
Content of the file main.avap
addVar(5, a) 
include utilities.avap 
include operations.avap

addVar(b, increment(a))
addVar( c, multiply(b, 2))
addResult(c)

Content of the file utilities.avap
function increment(x){
    return(x + 1)
}
Content of the file operations.avap
function multiply(x, y){ 
    return(x * y)
}
```

In this example,  `utilities.avap`  and  `operations.avap`  are imported into  `main.avap`  at the specified points, allowing the  `increment`  and  `multiply`  functions to be used in  `main.avap` .
