CONTENTS = context-string
The CONTENTS option identifies the context string of the highest-level or Contents topic. This topic is usually a table of contents or index within the help file. Windows Help displays the Contents topic whenever the user clicks the Contents button.
context-string
Specifies the context string of a topic in the help file. The string can be any combination of characters, except spaces, and must also be specified in a context-string \footnote statement in some topic in the help file.
If the [OPTIONS] section does not include a CONTENTS option, the compiler assumes that the Contents topic is the first topic encountered in the first listed topic file in the [FILES] section of the project file.
The following example sets the topic containing the context string
“main_contents” as the Contents topic:
CONTENTS=main_contents[FILES], [OPTIONS]
