## Syntax

```
t{start.column,}length
```

## Parameter(s)

| start.column | Specifies the position for extracting characters from an attribute. If not specified, the extraction begins from the same end of the string as the justification attribute 9, either l (left) or r (right). The start column must be numerical. |
| --- | --- |
| length | Specifies the length of extracted characters. The length is always counted from left to right, regardless of the justification specified in the attribute-defining item. The length must be a numeric. |

## Example(s)

This extracts ten characters,
beginning from the third position of the string.

```
t3,10
```
