Interesting, but IO is easy. What about multitasking? What kind of RTS
needs to be supplied for tasks to work correcly?

Note that this requires the C run-time instead. It might be smaller/
faster, but still it is not No_Run_Time in the strict sense. You might
need to really use the basic OS services directly to claim "no run-
time" program. Or even forget about OS, the No_Run_Time option is most
likely intended for those who program hardware directly.

No, I'm not "in class". :-)
