In the Ch 9 example: Data Validation, the book (p 295) says the format of Contacts.dat is fixed width, but later (p 296), an instruction says to pick a file format of ragged right. I have been typing in the examples myself, and looking at the data, the book seems to be wrong in both cases. I resorted to looking at the downloaded code, and that code picks a delimited (tab) format. The book indicates that the 'Columns' tab is used to 'visually define the columns' which seems an even more confusing statement given the actual data. Sometimes this book is just awful.
