[Coco] Basic09 6309 version

[Walter Zambotti]

It appears that the 6309 version of basic 09 has a few bugs in using functions expecting integer parameters.

Namely the MOD and INT functions are not working.

There may possibly be more functions similar to this that are not working.

Does anyone know how the 6809 version was modified to become the 6309?

Also what enhancements are provided in the 6309 version?

Is the source available so we can make further changes?

It's time to review the changes and try and fix the 6309 version or just stop using it in preference for the 6809 version.

Ok people what do we know?
