Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

 :hdref [refid=label] [res=number].
 
The :hdref tag creates a section reference. A section reference links a
section to a hypertext word or phrase. When the user clicks on the
hypertext, the system displays the corresponding section. A hypertext word
or phrase can be created by using the :hpt and :ehpt tags.
 
In the help source file, a section reference can be used anywhere in the
file, including before the definition of the section.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
refid      Identifies the section to display. The label value must be the
           section label or resource name that uniquely identifies the
           section and must be given in the id parameter of a :h tag or in
           the name parameter of a :h tag.
 
res        Identifies the section to display. The number value must be the
           resource number that uniquely identifies the section. It must be
           the number given in the res parameter of a :h tag.
 
Comments
 
If both the refid and res parameters are given, only the first parameter is
processed; the other is ignored.
 
Example
 
This example uses the :hdref tag to create a reference to the section
identified by the label "cpy.":
