INT 15 - TopView - "OSTACK" - SWITCH TO TASK'S INTERNAL STACK

	AX = 101Ah
Return: stack switched
Notes:	this call may not be nested; a second call must be preceded by a call
	  to "USTACK" (AX=1025h)
	while TopView requires many API calls to be executed while on the
	  task's internal stack, DESQview allows those calls to be executed
	  regardless of the current stack
