FEATURES

With the program SC-103PU you get a powerful and freely available
scientific calculator for the Palm platform. Apart from scientific
functions it also offers a full set of logical operations and conversions
between different numeric systems (HEX, DEC, OCT, BIN). Additionally the
calculator offers a units mode for easy conversions between different
units including currencies, as well as calculations with mixed units.
The program is designed in a way, that it simulates the visual and
operational aspects of a true calculator, such that the user will be
immediately familiar with its interface.

The calculator program automatically adapts to single and multi
color devices. High resolution displays of SONY Cli devices
and devices with Palm Operating System 5 and higher are
automatically detected and supported.

Available in three different languages: English, German and Esperanto.

REQUIREMENTS

* Palm Operating System version 2.0 or higher.

* MathLib: This is a free shared library that can be used by
any OS 2.0+ Palm program that needs IEEE 754 double precision math
functions. It's distributed under the terms of the
GNU Library General Public License, and is freely available with full
source code and documentation at
<http://www.radiks.net/~rhuebner/mathlib.html>.
It's not a part of the SC-103PU program; a copy is simply included in
this archive for your convenience.

INSTALLATION

If you don't know, how to install additional applications on your
Palm device, please refer to the instruction manual which is shipped with
your Palm device. 

Installation procedure:

* First, install the file MathLib.prc on your Palm device, if it isn't
already installed.
NOTE: Due to the fact that the MathLib is required by many Palm
applications, it is probably already installed on your Palm device and you
don't have to install it again. (The MathLib is not visible as an
application. If you are not sure if the MathLib is already on your
Palm device, then simply install it to be safe.) 

* Select one of the available language versions of the SC-103PU. You find
the various language versions in the subdirectories english, deutsch and
esperanto. Install the containing file SC-103PU.prc on your Palm device as
usual.

* Now you should find an application called SC-103PU in the category
"unfiled". If you select the corresponding symbol, the SC-103PU will be
displayed. 

NOTE: If you use the Esperanto version, you should activate a Latin-3
character set for this application. All tools necessary are available
for free at <http://purl.oclc.org/NET/pp-lat3>

TROUBLESHOOTING

If the SC-103PU crashes when used in combination with the hack TealLaunch
then update to the latest version of TealLaunch.
