        I'm not sure I understand exactly what you are describing in
        the first paragraph, but the second describes what is usually
        called "preemptive" multitasking.

        Cooperative multitasking is multitasking where a context switch
        occurs only when the current task or thread decides it is prepared
        to relinquish the CPU. This is usually done by calling an OS
        function, e.g. Yield(), which will either return immediately if
        no other task is ready to run, or perform a context switch if there
        is another task ready.

I meant to describe in the first paragraph programming
like I do state machine design for chips, where you DO
know all the possible states of your program,(it may
be a big set), or
if you can't define all the states in a problem, you
separate that problem and use another processor to
handle it so that you CAN define all the states in
the program at hand.  Then you dont need a preemptive
RTOS.

Thanks for the clear definitions.
