Multilevel 1.9 PDA

1. Introduction

The international version of  Multilevel 1.9 PDA is finally available!

From this very moment the software can be downloaded from the server. I switched from a download-based fee to web-page advertizing. The resulting revenues are primarily used for maintainance of this web-site and my non-profit decompression medicine research, which in turn will lead to safer diving procedures for the whole diving community. Please read the licence statement before you use the software.

Multilevel 1.9 PDA is the second international release of this decompression software and also the first version especially designed for personal digital organizers (PDA).The first German version dates back to 1996. It all started with an MS-DOS version, much like the famous "Dr. X". Several Windows - version were released afterwards, written in the powerful but platform- dependent C++ - programming language. In 1998 the Java Revolution provided the world with the fascinating possibility of a platform-independent programming language. I soon realized the huge potential and converted  my source code to Java. It was well worth the effort and I am sure, never to return to the C++ - world. Meanwhile I have the great pleasure, to provide the diving community with the first professional mixed-gas decompression software that is running on different platforms like Windows NT/95/98/XP/Vista, Windows CE/mobile, Linux, MacOS, Unix etc.......
In 1999 the first international version of Multilevel (version 1.6) was released.

Multilevel 1.9 PDA is remarkable in that it comes with a number of very useful features:

Attention: Multilevel has been tested with various operating systems and WWW-browsers, but problems might possibly occurr, since I have used the AWT- and not the (truly platform-independent) Swing - classes because the program had to be able to run on a simple WWW-browser under Java 1.02. Although the software has generally proven to be platform-independent, the GUI might have to be altered on particular operating systems. This can most probably happen with handheld PCs with small screens, operating on systems like Windows CE/Mobile or Palm OS.
However, generally speaking, the availability of JVMs on even exotic operating systems is steadily improving. Java has meanwhile earned a reputation of running on a lot of different consumer devices from mobile phones to Network PCs and has become more accepted than ever before. Please give me some sort of feedback on which platforms you have successfully tested Multilevel.
There can be no doubt that one of the most powerful platforms for Multilevel 1.9 PDA is the Sharp SL-5500, called "Zaurus".
Since Linux and Java are already on bord, this powerful handheld is certainly the best choice if you want to run Multilevel on a PDA.

Until this very moment the following platforms have proven successful:   
Operating System Java - Environment Remarks
Windows 98/NT/XP/Vista
Netscape, Firefox (Java Plugin), Internet Explorer
Windows CE/Mobile Microsoft JVM on Casio's Cassiopeia 
Embeddix Jeode JVM (preinstalled on the "Zaurus"!) Runs flawlessly on Sharp SL-5500
Linux Netscape Communicator 4.x or greater
MacOS Netscape Communicator 4.x or greater

Check to find a JVM for your platform. Please let me include your experience with Multilevel on this site!

And last but not least I would like to thank the members of Höhlenforschungsgruppe Ostalb/Kirchheim e.V. (HFGOK) and Höhlentauchsektion des Verbandes deutscher Höhlen- und Karstforscher (HTS-VdHK), who have supported the development and testing of Multilevel .
