Ok, here it is. A friend came over and made a quick animation with DPIII
(it shows the fundamental theorem of calculus). He created it planning to
be able to reverse parts of it (showing area increasing/decreasing as
x increases/decreases). Also, he put an opening screen up and a closing
screen up. Problems:

	1) The Director's ANIM command doesn't go backwards!!!! (Grrrr)
	
	2) Last Frame problems. I realize that you must check ANIM's
	   end parameter BEFORE displaying the resultant frame, but
	   even then we end up on the first frame!
	
	3) ANIM's abs and rel parameters aren't used. I guess DPIII
	   doesn't create that type of animation, but why not?
	
We can work around problems 1 and 3. 1 by buffering up the sequence
we want to reverse (too much memory) or by modifying the original
animation (more memory, but not too much). 3 by simply counting frames.

But problem 2 is a real bummer. DPIII saves and shows the animation
at the same time. When it gets to the last frame, it is still saving
and displays the first frame with the zz-cloud. Therefore we suspect
that DPIII is saving the first frame as the last frame of the animation!


Does anybody have similar problems or advise to give? I have
DPaint version 3.01 and the 6/14/88 version of Director.
