8.13.2.2 Listing topics for contents with and without subheadings
Suppose you use the same format for topics with subheadings and for topics without subheadings. The possibilities include:
Mixed “book” and “page” entries
No subheadings? You get “page” entries
To list all such topics as “books” in the contents file, assign to the format a B (“both”) level: one of [HelpCntStyles] properties B1 through B9. Mif2Go creates a “book” contents entry and a subordinate “page” entry for each.
To list all such topics as “pages” in the contents file, assign to the format a T (“topic”) level: one of [HelpCntStyles] properties T1 through T9. Mif2Go creates a “page” contents entry for each.
Mixed “book” and “page” entries
To list topics without subheadings as “pages”, and topics with subheadings as “books”, assign to the format a V (“variable”) level: one of [HelpCntStyles] properties V1 through V9. You can adjust the level numbers to fit the way you use your headings; this might take a bit of experimenting to get the effect you want.
No subheadings? You get “page” entries
When you assign V1 through V9, Mif2Go determines whether the format should be a heading or a topic, based on the existence of subheadings. However, a defect in WinHelp causes V entries without subheadings to be treated as though they were T. For example, a chapter heading for a single-topic chapter would appear as a “page” entry under the preceding chapter.
To list topics without subheadings as “books” (for example, if you have a single-topic chapter), you must assign a B level to the heading format instead of V.
