<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. </b>Runtime context data is the context in which a phrase is allowed to run,
|
|
though it's only used for rules. For example,
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>Before taking a container when the player is in the Box Room: ...</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">has the opportunity to fire when the "Before taking" rulebook gets to it.
|
|
But the rule only actually does so if the action is "taking a container"
|
|
and the condition about the location applies, and these two stipulations
|
|
form the PHRCD for the rule. For some simpler rules, like:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>When play begins: ...</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">the PHRCD remains empty, because they are guaranteed to fire whenever their
|
|
rulebooks reach them.

with the correct rulebook variables or it won't parse; but the rulebook

variables won't be known until the rule is booked; and in order to book

the rule, Inform needs to sort it into logical sequence with others

already in the same rulebook; and that requires knowledge of the
