I'm pretty sure you'd have to install an interrupt routine that would
restart your program...I can't think of any other way you could do it. I
think an interrupt routine something like this should work:

   bit onRunning,(iy+onflags)
   ret z
	;I'm not sure exactly how to use _exec_assembly, but use it here to
	;restart your program - you could pass it some value that would let
	;it know where to pick up.
   res 2,(iy+35)	;uninstall interrupt
   ret
