basically you can't. Oberon has its own modules that take care of file
access, process creation, etc.

Patrik Reali wrote a Java compiler for Bluebottle, but I'm don't know
what the current status is.

The compiler is part of Bluebottle, you can compile your Oberon programs
in Bluebottle/Oberon. The source code of the compiler is included.

I'm not sure if you got the right idea...Oberon is a language and a
runtime environment. Under Linux, running Oberon will open a window with
the typical Oberon user interfacee. You can the program or do whatever
you like 'inside' that window.

after you understand the system, you'll probably need a day or two to
finish your first user interface ;-)

if you have never installed Bluebottle on any partition before, you
don't need to execute that command.

IDE0#00 is the whole disk, so IDE0#1 would be appropriate

Remove the "!". The exclamation mark is only there to protect you from
accidentally overwriting your boot record.

Right. Replace <from> with the actual partition type (IDE0#1 has type 14
 as you can see from Partitions.Show's output).
The command you want to execute is:
Partitions.ChangeType IDE0#1 14 76 ~

Follow follow the instructions in AosInst.Tool carefully!

Good luck
