For instance, if we write 'Zero hour is a time that varies', but don't tell Inform anything specific like 'Zero hour is 11:21 PM.', then Inform uses the value in the table above to decide what it will be. The same applies if we create a property (for instance, 'A person has a number called lucky number.'). Kinds of value not included in the table cannot be used in variables and properties.<hr></td></tr><tr style="display:none" id="repeat"><td colspan="5">A tick for <b>repeat</b> means that it's possible to repeat through values of this kind. For instance, 'repeat with T running through times:' is allowed, but 'repeat with N running through numbers:' is not - there are too many numbers for this to make sense. A tick here also means it's possible to form lists such as 'list of rulebooks', or to count the 'number of scenes'.<hr></td></tr><tr style="display:none" id="props"><td colspan="5">A tick for <b>props</b> means that values of this kind can have properties. For instance, 'A scene can be thrilling or dull.' makes an either/or property of a scene, but 'A number can be nice or nasty.' is not allowed because it would cost too much storage space. (Of course 'Definition:' can always be used to make adjectives applying to numbers; it's only properties which have storage worries.)<hr></td></tr><tr style="display:none" id="under"><td colspan="5">A tick for <b>under</b> means that it's possible to understand values of this kind. For instance, 'Understand "award [number]" as awarding.' might be allowed, if awarding were an action applying to a number, but 'Understand "run [rule]" as rule-running.' is not allowed - there are so many rules with such long names that Inform doesn't add them to its vocabulary during play.<hr></td></tr><tr><td style="white-space:nowrap;" align="left" valign="top" height="20"><font face="lucida
