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.

3.6.1 Data Type of Locations		Specifying a data type for locations.
3.6.2 Actions and Locations		Using locations in actions.
3.6.3 Default Action for Locations		Defining a general way to compute locations.
