Check it out if you are interested in some good numerical analysis stuff in Ada. Can someone from AFIT reading this ask one of the authors (i.e. Raduenz, Suter or Christensen) to post the source code (68 lines of code) to comp.lang.ada, so that others can benefit. I would also like to point out why the DoD needs an active reuse software effort along the lines of the Greg Aharonian style, becuase there are many such pieces of Ada code ranging from a few hundred lines to a few hundred thousand lines of Ada code available, but that no one knows about or that get into any of the repositories because no one is doing the equivalent of this comp.lang.ada posting. (Though maybe VCOE/SPC plan to spend some of their $7.5 million reuse dollars training high school teachers how to do this). Diatribe aside, it is a nice article with some nice code. -- ************************************************************************** Greg Aharonian srctran@world.std.com Source Translation & Optimization 617-489-3727 P.O.
