Folks,
Here is an interesting discussion on the [BUGS] mailing list. BUGS has
to do with statistical modeling (Markov Chains Monte Carlo).
Just thought you might be interested (a little) or could give Bill
Northcott some comments.

The following item appears in the 'ToDo' list on the openBugs site:
Port ClassicBUGS to Java byte code using Garden Point Compiler.

Has anyone seriously looked at this? If so are they interested in
cooperating to make it happen?

I had bit of look: got the Garden Point compiler, built some short java
code programs with it and had a poke about to see what is in the
package.

This is the list of things that need to be done as I can see it at this
stage:
File name/format issues
    1. Oberon's Black Box uses the extensions .odc for source files and
.ocf for symbol files.
         GPCP uses .cp for source and .cps for symbol files.
    2. GPCP source files are plain text. Is there some way to do a
batch conversion of odc files to text in Black Box?
    3. Executable formats are totally different, but we are only
looking for source code compatibility. So that's unimportant.
    4. Black Box uses resource files like many GUI based platforms. As
far as I can see,except for the GUI modules, these only contain error
text, which could be incorporated into the code .

Libraries
   1. Some BUGS modules import modules from the Black Box base. As far
as I can see, except in the GUI stuff, there are only a few of these -
Maths etc. GPCP seems to provide symbol files to replace these
functions with ones from the standard Java (or .NET) libraries.
   2. There are some potentially curly issues such as WinBUGS providing
its own random number generator, because there does not seem to be one
in the Black Box framework. Other platforms like Java or .NET provide
random number generators. Should we use functions from other
platforms, or stick to BUGS ones?
