# Repeating (looping)

### @index <a href="#index" id="index"></a>

* no parameters
* returns a whole number

`@index` — no parameters or parentheses necessary — returns the current iteration number if this function is called from within a “loop”, i.e. when the software cycles between the elements of a list. This is for example the case when [repeating a row in a table](/clauses/introduction-to-tables.md#repeating-rows), or when going through repeating clauses. `@index` will return zero if used outside a loop.

For example, if `#customer^name` is a repeating list that contains the names “John Smith”, “Jane Doe” and “Marie Thompson”, then the following output would be produced in a table with a repeating-row . The @index starts at 1, and is then incremented with each additional row, until the end of the loop.

{% hint style="info" %}
Note that (unlike most programming languages) the returned number is one-based, i.e. the first iteration in a loop will be one (not zero).
{% endhint %}

{% hint style="success" %}
To get the row-index in the context of a [Q\&A column condition](/qna/adding-conditions.md), use `@row-index` instead.
{% endhint %}
