Creating page groups
You can create page groups in AFP files. Page groups organize AFP files into smaller, uniquely identifiable units. When you create page groups, any existing page groups defined in the AFP file itself are not used.
The sample AFP file must contain page groups before you can define header and trailer pages, create index tags for a page group, or make any other enhancements. If page groups are defined in the AFP file itself, you can use these page groups or you can create new page groups.
