*scr.Screen = Peek.l(Addr Screen(0))

BitMap 0,*scr\Width, *scr\Height, *scr\RastPort\BitMap\Depth
BltBitMap_ *scr\RastPort\BitMap,0,0,Addr BitMap(0),0,0,*scr\Width,
*scr\Height,$C0

SaveBitMap 0,"ram:grab.iff"
Hope that helps. I'm not sure how to grab the palette from the screen,
but I can send you that code for getting a list of screens if you want.
