This is a response to VC 17 Paul 6 ("Mac Toolbox")...
Thanks, Paul for your comment on the book on Lightspeed C, Using the MacIntosh toolbox with C. It covered much of the material covered in the MacIntosh Programming Primer and in a different way. It helps to work through both of them.
When I went to look for the book, I found that Book II of the Macintosh Programming Primer was out. It continues on where book 1 left off. I looked thru it and it looks as if it is going to be helpful.
I got lightspeed C 4.0 and the object oriended additions to the language look like they will really help in programming.
