It's all explained in chapter 16 of the book:

16.1.1 Retrieving information about the fields (part 1)
explains how to get the field type, the value of a Text
field and the possible values of Choice (list, combobox)
and Button fields (checkbox, radiobutton).

16.1.3 Retrieving information about the fields (part 2)
explains how to retrieve the page number of the fields,
the position, and a lot of other internal field information.

Section 16.1 and 16.2 explain how to change all these
values (as long as we're talking about AcroForms, not XFA
forms).
best regards,
Bruno
