I suppose so, though I don't know the details of those
very well. As I understand it, IBM doesn't say much.
One that I didn't think about before that post is how to do it
independent of the OS. If the processor manufacturer generates the
conversion program, it has to be written in an OS independent fashion.
At least the details of the intermediate code should be open.
Hopefully it wouldn't make decompilation any easier, such that vendors
would be worried about secrets getting out.
[The AS/400 architecture tightly integrates the operating system and the
architecture. There's a virtual machine language that hasn't changed
in decades, even though the physical implementation has changed from
LSI bit slice to powerpc chips. I doubt you can do this in an OS
independent way; that way lies the swamp of UNCOL. -John}
