# Variables Name

A variable can have a short name (like x and y) or a more descriptive name (age, carname, total\_volume). Rules for ChardScript variables:

* A variable name must start with a letter or the underscore character
* A variable name cannot start with a number
* A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and \_ )
* Variable names are case-sensitive (age, Age and AGE are three different variables)

#### Example

Legal variable names:

{% code lineNumbers="true" %}

```renpy
call myvar = "John"
call my_var = "John"
call _my_var = "John"
call myVar = "John"
call MYVAR = "John"
call myvar2 = "John"
```

{% endcode %}

Illegal variable names:

<pre class="language-renpy" data-line-numbers><code class="lang-renpy">call 2myvar = "John"
<strong>call my-var = "John"
</strong>call my var = "John"
</code></pre>

{% hint style="info" %}
Remember that variable names are case-sensitive
{% endhint %}

### Multi Words Variable Names

Variable names with more than one word can be difficult to read.

There are several techniques you can use to make them more readable:

### Camel Case

Each word, except the first, starts with a capital letter:

{% code lineNumbers="true" %}

```renpy
call myVariableName = "John"
```

{% endcode %}

### Pascal Case

Each word starts with a capital letter:

{% code lineNumbers="true" %}

```renpy
call MyVariableName = "John"
```

{% endcode %}

### Snake Case

Each word is separated by an underscore character:

{% code lineNumbers="true" %}

```renpy
call my_variable_name = "John"
```

{% endcode %}
