Unformatted text preview: Programming in System RPL Eduardo M Kalinowski Carsten Dominik Second Edition Preface to the Second Edition Back in 1998, when the first edition of this book was released, it proved to be a good tutorial for new learners of System RPL, and also a good rerefence for more experienced programs. However, there was still room for improvement. And when the HP49G calculator was released, the need for a second edition of this book was even greater, because no document describing all its new features existed. For these reasons, we have put together this new edition. Those who have used the first edition of this document will find many changes and im-provements, and also some 400 additional pages :-). The structure of the book has been totally changed, with the tutorial and reference parts merged. All the text has been revised and corrected. Some chapters were completely rewritten in order to make them easier to understand and more useful. There are also new chapters, describing new HP49 features, and also about things that were not described in the first edition. We hope this book is a valuable resource for those that already knew System RPL on the HP48 and wanted more information on the new HP49 fea-tures, and for those that want to start learning System RPL in order to discover more of the power of the HP49. April 24, 2002 Eduardo de Mattos Kalinowski Carsten Dominik i Preface to the First Edition The programming features of the HP48 graphical calculator are very powerful. They allow you to do virtually anything. However, the documented programming functions, that are directly accessible to the user (the user lan-guage), is not everything the calculator can do. There is another language: the System language. The User language is a subset of the System one, with just some commands and just a fraction of its power. However, the System language is not well documented. The existing documents on that subject are turned to someone who already knows it; they are just listings of the commands with some brief descriptions. Once you al-ready know the language, even the brief descriptions can be left out, and those documents are really a very good source of information. But how does one learn System RPL? The purpose of this book is exactly that: to be a way for someone who has already learned User RPL (if you have not yet, learn it before, then come back to this), and wants to learn the real power of the calculator. July 12, 1998 Eduardo de Mattos Kalinowski ii Acknowledgments This work could not have been accomplished without the help of many people. Firstly, we would like to thank Mika Heiskanen for his entry point list by subject. That document was an important source of information. His JAZZ library with its disassembler and other functions was also an indispensable gateway to the HP48 ROM code....
