<p class="commentary firstcommentary"><a id="SP4" class="paragraph-anchor"></a><b>§4. </b>The <span class="extract"><span class="extract-syntax">{-A}</span></span> ("past actions") escape.
|
|
A series of <span class="extract"><span class="extract-syntax">if</span></span> statements checking whether each past-tense action is now
|
|
true, and updating the relevant array entries accordingly.
|
|
</p>
|
|
|
|
<p class="commentary">This looks straightforward, but a tricky point arises from the fact that a
|
|
turn is not the same thing as a slot for an action. Usually they correspond,
|
|
but not always. So if the action for a turn is taking, and that causes
|
|
a further action of opening a box, say, what do we say about the number
|
|
of turns for which the taking and opening actions have been happening?
|
|
</p>
|
|
|
|
<p class="commentary">In <span class="extract"><span class="extract-syntax">adjust</span></span> mode, we are at the start or end of a "try" action which
|
|
arises mid-turn. As can be seen, adjust mode is allowed only to change
|
|
the record of how many turns an action has been happening — from 0 to 1,
|
|
and otherwise making no change, if the action is the one being tried;
|
|
or else back to 0 if it isn't. In particular, an action implicitly
|
|
tried does not affect the "times" count.
|
|
</p>
|
|
|
|
<p class="commentary">This is a delicate business. The better way to solve this would be to
|
|
stack a local copy of these arrays each time an action starts, and restore
|
|
it (with updates) each time it finishes. But there is just no storage
|
|
available in the Z-machine to contemplate this with equanimity, so we
|
|
compromise. Historically, it's been a fertile source of tricky bugs.
|
|
The test case <span class="extract"><span class="extract-syntax">ActionInterrupted</span></span> should be checked if this code is
|
|
ever tampered with.
