Description
Use Topic ID to display topic, specifying page anchor.
The RTL Help System calls DisplayTopic to have the Viewer handle a topic-based Help request and can specify a page anchor. If the page does not have the page anchor, the page is opened anyway.
Topic is the Topic ID, a short string that must be unique for all topics maintained by a particular Viewer.
Anchor is a tag that allows you to jump to a specific place in a page.
