Examples ******** Now we show and explain three sample programs written using Bison: a reverse polish notation calculator, an algebraic (infix) notation calculator, and a multi-function calculator. All three have been tested under BSD Unix 4.3; each produces a usable, though limited, interactive desk-top calculator. These examples are simple, but Bison grammars for real programming languages are written the same way. You can copy these examples out of the Info file and into a source file to try them.

- RPN Calc
- Reverse polish notation calculator; a first example with no operator precedence.
- Infix Calc
- Infix (algebraic) notation calculator. Operator precedence is introduced.
- Simple Error Recovery
- Continuing after syntax errors.
- Location Tracking Calc
- Demonstrating the use of @N and @$.
- Multi-function Calc
- Calculator with memory and trig functions. It uses multiple data-types for semantic values.
- Exercises
- Ideas for improving the multi-function calculator.
