| #      | Length operator        | Applicable to string values. The result is an integer.                                                                                           |

## **Assignment operator**

It has the following form:

`variable1, variable2, …, variableN = expression1, expression2, …, expressionN`

In its simplest form variable `= expression`.

## **Return operator**

It is written as an expression and should be at the end of the statement block.

## **Empty operator**

Written as `;`.

## Example

A statement block with two assignment operators and a return operator:

```
a, b = 1, 2; -- assignment operator and empty operator
c = 3; -- assignment operator and empty operator
a + b + c -- return operator
```
