─────Control Characters─────────────────────────────────────────────────────
 
     Using the /A option, you can specify an application control
     character. This control character marks the beginning of a line
     that contains control codes being passed to the application
     displaying help. An alternative method of passing control codes is
     to use dot commands.

          ◄Dot Commands►
 
     Within the help databases provided with Microsoft applications, a
     colon (:) is used as the control character. The following codes
     are supported in most applications:
 
     Control Code   Action
 
     :ln            Sizes the help window to <n> vertical lines. The
                    line with this code should follow the last context
                    definition for the topic. You can also use the
                    .length dot command.
 
     :ntext         Defines <text> as the title of the topic text. The
                    application may display this title at the top or
                    bottom of the help window. The line with this code
                    should follow the last context definition for the
                    topic. You can also use the .topic dot command.
 
     :zn            "Freezes" <n> lines at the top of the topic. Frozen
                    lines do not scroll. This code can be used to
                    prevent a screen title or row of "buttons" from
                    scrolling out of view. You can also use the
                    .freeze dot command.
