   This is a hypertext card that contains three links: the NEXT button
   can be used to select HYPERTEXT CARD 2, the PREV button can be used
   to select HYPERTEXT CARD 3, and the BTRK button can be used to select
   the last card displayed (either HYPERTEXT CARD 2 or 3).

   The display attributes for the links are defined by the %%linkdef
   commands in the GLOBAL DEFINITIONS area at the top of the file.

   The display attributes for the card titles and other text are defined
   by the %%attrdef commands in the GLOBAL DEFINITIONS area. The display
   attributes named bold_yellow are used for card titles and the attributes
   named green are used for the rest of the text.

                             %attr(bold_yellow)HYPERTEXT CARD 2

   You can change display attributes at any point in the text of a card.
   For example, this is%attr(bold_yellow)BOLD YELLOW%attr(green), %go
and this is not.

%card_end(card_2)

%card(card_3,green,3)
%link("NEXT",card_1,next) %link("PREV",card_2,prev) %link("BTRK",,btrk)

                             %attr(bold_yellow)HYPERTEXT CARD 3

   You can also use the %%tx command to switch back to the default
   display attributes. For example, this is%attr(bold_yellow)BOLD %go
YELLOW%tx()and this
   is not.

%card_end(card_3)
