# Programming HP Calculators

**Note:** Everything mentioned in this manual should work with all Hewlett Packard graphical calculators unless otherwise stated, however this manual has only been tested for commands and variables compatible with the 38g series of calculators.

This book does not work with HP 28 or HP 48 series graphical and scientific calculators. This series used a FORTH like programming language and also provided a symbolic calculation mode. *Maybe someone wants to provide material about this series?*
