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.

Platform Support
The following platforms are/will eventually be supported:

Platform	Status
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:

Language	Status
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 language.

Additional Information
Additional information is available on:

• Taurus OPL Library - the opl2java support library
• 1.10 Release Notes
• House demo
• Patience demo

The package interface developed for opl2java is available as a native implementation on the Psion as part of my Psion JavaVM.
