the usual computer-science sense of "Is this true or false?". Here a subject

is in one of a finite number of possible states, as declared by a sentence like:

</p>

<p>The cask can be wedged open, bolted closed or stoved in.</p>

<p class="commentary">A property called the "cask condition" is created, whose value must be one of

these three named possibilities; and this is also the name of a new kind,

which is an enumeration of which these are the only three legal values.

<p class="commentary firstcommentary"><a id="SP3_3" class="paragraph-anchor"></a><b>§3.3. </b>The name is ideally the subject's name plus "condition": for instance,
|
|
"lounge table condition". But we need to be careful in case there are
|
|
multiple such conditions, because we don't want to duplicate the name. So
|
|
we begin by counting how many such already exist, and then append a number:
|
|
thus "lounge table condition", then "lounge table condition 2", and so on.
|
|
</p>
|
|
|
|
<p class="commentary">We could be more fanatical about this, if we wanted. The code here doesn't
|
|
guarantee uniqueness of the resulting name in all cases, because it's possible
|
|
for two subjects to have identical names. (But when that happens, it's unlikely
|
|
that different condition properties are given to them.) We won't obsess over
|
|
this because the point is only to help the user by minimising namespace
|
|
clashes; it isn't essential to Inform's running.
