	The functions you are talking about are available through hooks
in the O/S which handle scheduling.  PC/MS-DOS are single tasking operating
systems and therefore do not have a scheduler which controls time usage.

	I am not really that familliar with Double DOS, but I would doubt
that it has the sophistication of a real multi-tasking operating system.
What they are probably doing is splitting clock ticks between the two 
applications that are running.
