t{start.column,}length
| 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. |
This extracts ten characters, beginning from the third position of the string.
