```

### Arguments

| Argument | Type              | Required | Description         | Default |
| -------- | ----------------- | -------- | ------------------- | ------- |
| `array`  | `assignablearray` | `true`   | The array to modify |         |
| `start`  | `any`             | `true`   | The starting index  |         |
| `end`    | `any`             | `true`   | The ending index    |         |

## Examples

### Tag Syntax

```java
<bx:set MyNewArray = arrayNew( 1 ) > 
<!--- ArrayToList does not function properly if the Array has not been initialized with arraySet. ---> 
<bx:set temp = <!--- Transpiler workaround for BIF return type --->(( <bx:argument>, <bx:argument>, <bx:argument>, <bx:argument> ) => <bx:set arraySet( arg1, arg2, arg3, arg4 ) ><bx:return true>)( MyNewArray, 1, 6, "Initial Value" ) > 
<bx:output>#ArrayToList( myNewArray, ", " )#</bx:output>
```

Result: Initial Value, Initial Value, Initial Value, Initial Value, Initial Value, Initial Value
