I have been working with these programs recently.  I am by no means and
AI expert but for my needs they are quite sufficient.  I posed a question
to this group a few weeks ago.  With a few hours of serious study, I was
able to adapt the back propagation program to solve the problem and give
some meaningful results.  To this extent, the programs are useful in the 
real world.  

On a related note:  The back propagation program was running a little 
slow on my PC.  Fortunately, the source code is included in the package
and I was able to get the programs running on our departmental mainframe
in about 10 min, drastically reducing run times.
