I understand the concept & practice of "High Level Programming Languages", but find it hard to believe that there would not be a significant amount of platform specific code that must be written for each architecture. Specially for a project as large as this one being proposed, but I will be happy if "After-the-Fact", when the project is completed, I am proven wrong, and there is almost zero platform specific code that is needed. I don't know what version of MUI AROS can use, or if it is used at all, as I am not familiar with AROS, but my limited understanding of AmigaOS4.x and MorphOS3.x suggest that quite a bit of coding for MUI4 on MorphOS3.x, and ReAction for AmigaOS4.x, would make the platform differences between the two binaries a significant amount of coding, but a small percentage of the total coding for each project.

As always, thanks for the reminder and link to our previous conversation.
