3.6 Tracking Locations
Though grammar rules and semantic actions are enough to write a fully functional parser, it can be useful to process some additional information, especially symbol locations.
The way locations are handled is defined by providing a data type, and actions to take when rules are matched.

| 3.6.2 Actions and Locations | Using locations in actions. | |
| 3.6.3 Default Action for Locations | Defining a general way to compute locations. |
