Even that is TSR based, not a real multi-tasker.<br>
Under DOS a process can be swapped out and re-activated by a
hardware interupt, either f.e. a timer or the keyboard.<br>
So, at most, co-operative multi-tasking in the sense that multiple
processes can run at the same time.<br>
Because DOS is non-re entrant real multitasking will be very hard to
achieve. It would be done by now ;)<br>
