< p class = "inwebparagraph" > < a id = "SP2" > < / a > < b > § 2. < / b > Instances are named constants of kinds which have a finite range (unlike
"number", say), and where the possibilities are entirely up to the source
text to specify (unlike "truth state", say), and where the values form
part of the model world, so that inferences can be made about them, and
properties attached to them, and so on (unlike "rulebook", say). For
example, in
< / p >
< blockquote >
< p > Colour is a kind of value. The colours are red, blue and green.< / p >
< / blockquote >
< p class = "inwebparagraph" > three instances are created: "red", "blue" and "green", which are
constants of kind "colour" made to differ from all other known "colour"
values (including each other). Objects are instances too:
< / p >
< blockquote >
< p > Peter carries a blue ball.< / p >
< / blockquote >
< p class = "inwebparagraph" > creates two instances of "object" (though the world-model-completion code
will eventually make them instances of the subkind "thing" unless other
evidence turns up to suggest otherwise).

Inform source, a brief explanation. Inform's world model is brought into being
by assertion sentences; these are converted to logical propositions; and
the propositions then "asserted", a formal process of arranging the world
so that they become true. Since some propositions assert the existence of
instances, the process sometimes means calling the following routine.
What makes it "protected" is that it is not allowed to be called from
anywhere else, and any attempt to do so will throw an internal error. (This
ensures that we don't accidentally break the rule that the model world is
fully specified by the propositions concerning it.)

Inform traditionally allows these for instances of object, but not for other
instances: thus "submarine green" (a colour, say) must be spelled out in

"object" has a whole hierarchy of subkinds, there's no unique numbering —
the same object may be thing number 17 but vehicle number 3 — and secondly,
because we won't know the exact kind of objects until much later on; for now
the only thing we are sure of is that they are indeed objects. Enumerations
for objects within kinds is certainly useful, but it's harder to do and will
be done later on: see the "Instance Counts" plugin.

a way that they need to be given additional structure. For example, the

ending, and so on. To achieve this, each instance is allowed to have a
single pointer to another data structure.

when their kind's name coincides with a name for a property, as might for

that a ball might have a colour, we can declare that "the ball is green",
or speak of "something blue": whereas we are not allowed to use "score to
beat" adjectivally since (a) it is a variable, and (b) "number" is not a
coinciding property: we would not ordinarily write "the ball is 4". (A
quirk in English does allow this, implicitly construing number as an age
property, but we don't go there in Inform.)

instance, though a noun, must be used as an adjective: for example, "red".
Inform has run through the permissions for the property ("colour") in
question, and found that, say, it's a property of doors, scenes and also
a single piece of litmus paper. Each of these three is an inference subject,
so < code class = "display" > < span class = "extract" > InferenceSubjects::make_adj_const_domain< / span > < / code > was called for each in turn.
By different means, those calls all ended up by passing the buck onto the
following routine: twice with the domain < code class = "display" > < span class = "extract" > set< / span > < / code > being a kind (door and then
scene), once with < code class = "display" > < span class = "extract" > set< / span > < / code > being null and < code class = "display" > < span class = "extract" > singleton< / span > < / code > being an instance
(the litmus paper).
