I've just imported a ~150 topic help file into FrameMaker. Each topic is a separate .fm file (usually short) that starts with a Heading 1.
I'd like to divide those .fm files into chapter segments, insert a chapter-title .fm at appropriate points, and print the resulting book file like a regular book. The TOC organization and file lengths look like this:
One hack would be to author and maintain the source document as the present book, but have a separate monolithic FM document that imports all the book content as text insets. As long as the lead headings, presently starting new pages due to being in separate files, do NOT have Top of Page properties, it should be continuous flow.
I've created entirely parallel books this way, where the clones import the content of the "real" book, in order to have pro vs. consumer or domestic vs. export manuals, for the same product, with different page layouts, different conditionals, etc, (but not to defeat file-starts-on-new-page).
