Taurus opl2java Translator|
The opl2java project translates OPL code from the Psion Series 3x directly
into Java, allowing you to run your old Psion apps on either your PC or your
Series 5 when a JavaVM becomes available. My
JavaVM project enables you to run the
Java code on your Series 3x as well.
The OPL to Java Translator project started life as an OPL to C translator for
running some of my OPL applications on my old Archimedes machine. It worked
quite well, but menus and windows did not work at all well due to major
differences between the two GUI environments.
After I switched to programming in Java, I had a second crack at the job and
changed the code generator to produce Java source code. Ideally I would like
it to produce Java class files, which would speed-up the compilation process
by a goodly margin, but source code is much easier to develop with.
The following platforms are/will eventually be supported:
|Intel 386, Windows 95/NT||1.20 (Not downloadable)|
|Intel 386, Linux||(Planned for 2000)|
Output Language Support
The following languages are/will eventually be supported:
|Java Applet/Application||Since 1.00|
|C for Acorn RISCOS||Since 0.10|
OPL Language Support
The translator supports all the OPL programming language constructs, plus a
large number of OPL built-in functions and procedures. The built-in functions
are implemented in a separate OPL library, which must be built for each target
Additional information is available on:
The package interface developed for opl2java is available as a native
implementation on the Psion as part of my Psion JavaVM.
