In this case I don't understand how FPC is useful at all. I cannot
create executable files for such a device...

C has some language constructs for OS or driver implementation, e.g.
"interrupt". Should we add these to the OPL, to make FPC/OPL compete
with gcc/C? It would be nice, though, to have an Pascal DDK for Windows ;-)
Abstract: Even if it's easy to add privileged instructions to every
machine, the ordinary user IMO should be protected from using them.
