Free versions of the SPARK tools are available at http://www.praxis-his.com/sparkada/sparkbook.asp These are intended for those who have read Barnes' book. All versions of the SPARK tools are written in SPARK and thus have static-sized internal structures; the structures in the free versions are relatively small, so the size of projects that they may be used for is fairly small. -- Jeff Carter "Crucifixion's a doddle."
