Suppose you have a section of code or source that you need to include in several different passages. It could be a status display, or a few lines of descriptive text. Instead of manually copy-pasting it into each passage, consider placing it all by itself in another passage, and using (display:) to place it in every passage. This gives you a lot of flexibility: you can, for instance, change the code throughout the story by just editing the displayed passage.
Text-targeting macros (such as (replace:)) inside the
displayed passage will affect the text and hooks in the outer passage
that occur earlier than the (display:) command. For instance,
if passage A contains
(replace:"Prince")[Frog], then another passage
Princes(display:'A') will result in the text

such as writing
$var in place of
