"Macintosh Pascal Programming Primer Volume I"
ISBN 0-201-57084-X
s/Pascal/C/ if you want the C version. That ISBN is for the one I have. There may be a couple versions with updates etc.
The pascal version I have knows nothing of System 7, whereas the C version I have has been updated with System 7 info. I code for System 6, but it's nice to have your programs run on System 7-9, especially if you're going to be developing on them.
*I* think it's a good primer, but I'm not guaranteeing you'll like it. I have 3 different pascal for mac books, and it's by far the best of the three. Not a huge sample though.
I have all of the sample code on a CD if you want it. The code isn't exactly as it is in the book, it's been updated a bit, with compiler options that sometimes break things for Think Pascal. Maybe the exact source is available online; I haven't looked.
If it does, it doesn't matter. I've never found it to be an issue.
