More on Interrupts:

Dos is non-reentrant.  The reason being that when a system call 
is made, DOS switches over from the user stack to an internal fixed 
size stack.   Therefore a DOS call cannot be made unless you are
positive that DOS is not currently executing.


Sorry for the previous misinformation.
