		I would like to perform an fft using the DSP processor
	of the NeXT.
		So I am calling 'DSPAPfftr2a' and I would like to
	perform several computations on the result of the fft. The NeXT
	documentation says that the result is scrambled, and to use
	'DSPAPvmovebr' to unscramble it.
		The problem is that there is no example of what the
	parameters should be. It just says that the inSkip parameter should
	be count/2.  (Assuming count is the number of points of the fft.)
	But what about the other parameters ?

		Thanx in advance.
