PRINT CONVENTIONS
Please note:
Throughout this manual, standard font is Arial. Specific terms, names or titles are
printed in italics. Hyperlinks are underlined. Bold italic letters like n are used for va-
riables. Calculator commands e.g. ENTER are generally called by their names,
printed in capitals for easy recognition. Each and every command featured is listed in
the Index of Operations below.
This font is taken for explicit references to keys.
Register addresses are printed using bold Times New Roman, while lower case italic
letters of this font are employed for register contents. So, for example, y lives in stack
level Y, r45 in general purpose register R45, and alpha in the alpha register, re-
spectively. Overall stack contents are quoted in the order [ x, y, z,
All this holds unless stated otherwise explicitly.
GETTING STARTED
If you know how to deal with a good old HP RPN scientific calculator, you can
start with your WP 34S right away. Use the following as a reference manual.
Else we recommend you get an HP-42S Owner’s Manual. It is available at low
cost on the DVD distributed by the Museum of Hewlett-Packard Calculators
(www.hpmuseum.org). There are also other sources in the internet.
Please read Part 1 of said manual as a starter. This part includes an excellent
introduction to RPN. This RPN is a very effective method making , , , ,
, and keys obsolete in calculations. Once you got used to it you will
most probably never employ a calculator featuring again.
Part 2 of said manual will support you when you are heading for programming
your WP 34S for easy handling of repeated or iterative computations. Further
documentation, also about the other calculators mentioned above and in the fol-
lowing text, will add valuable information it is all readily accessible on a single
DVD from said source.
Most commands on your WP 34S will work as they did on the HP-42S. This little
manual here is meant as a supplement showing you all the new features. It contains
all the necessary information including some formulas and technical explanations but
is not intended to replace textbooks about mathematics, statistics, physics, pro-
gramming, or the like.
The following text starts presenting the keyboard as it will be active in various modes,
so you know where to find what you are looking for. It continues explaining the mem-
ory, addressing items therein, the display and indicators used to give you feedback
what is going on. Then the major part of this booklet is taken by the index of all the
operations, catalog contents, constants and conversions featured. It closes with a list
of messages the WP 34S will display if special conditions prevent it from executing
your command as expected.
