There are two ways to do it.

Chain procedure

	_Chain

	(A0): pointer to the applications file name
       4(A0): integer specifying the configureation of the
	      sound & screen buffers.

	This starts up the application without doing anything to the app.
	heap, keeping the calling applications data around in the heap.

	_Launch

	same parameters

	This is the same call made by the finder when starting an application.


	the integer in 4(A0) can have the following meanings.

	4(A0)		meaning
	---------------------------------
	0		use main screen & sound buffs
	<0		use alt sound & main Screen
	>0		use alt sound & alt Screen


	Just a warning,  I think the Mac SE and The Mac II don't have
	alternate buffers so beware.
