Apparently, John Barnes and a few others, were a little confused about 
some comments I recently made concerning his book "Programming in 
Ada95".  What follows is part of my reply to Barnes -- which should clear up 
everything.

Actually, John, I feel that the new book is much much better than the old
one.  Unfortunately, I don't have a copy of the old edition here in my
office, so I cannot give you any specifics.  However, the fact that
"things are more interwoven in 95" makes it much more useful for teaching
Ada.  I realize that these changes were not that significant from the
writer's viewpoint; however, from the reader's viewpoint they can be very
significant.  This is especially true if someone is learning Ada95 for the
first time.  In fact, I feel that your book is the best book for teaching
an experienced programmer Ada95. 

I do agree that the new book contains all of the information which was in
the old book, so it still does make an excellent handbook.

Keep up the good work!

This is the book that I'm currently learning from.  I'm really
enjoying the read, it's keeping me almost as hooked as a good
espionage novel!  :-)

I'm still quite in the dark about how to structure a large package,
and whether I should be using child packages or not for some various
implementations of things, but I suppose I'll have patience and maybe
that will get explained later.
