<p class="commentary">The <span class="extract"><span class="extract-syntax">@aread</span></span> opcode is a valid Z-machine opcode, but owing to the way I6 handles
the irreconcilable change in syntax for the same opcode in V3 and V4-5 of the

As a dodge, we use the Inform 6 statement <span class="extract"><span class="extract-syntax">read X Y</span></span> instead.

<p class="commentary firstcommentary"><a id="SP6_1_1" class="paragraph-anchor"></a><b>&#167;6.1.1. </b>Here we need some gymnastics. We need to produce a value which the
sometimes shaky I6 expression parser will accept, which turns out to be
quite a constraint. If we were compiling to C, we might try this:
</p>
<pre class="displayed-code all-displayed-code code-font">
<span class="plain-syntax"> (</span><span class="identifier-syntax">a</span><span class="plain-syntax">, </span><span class="identifier-syntax">b</span><span class="plain-syntax">, </span><span class="identifier-syntax">c</span><span class="plain-syntax">)</span>
</pre>
<p class="commentary">using the serial comma operator &mdash; that is, where the expression <span class="extract"><span class="extract-syntax">(a, b)</span></span>
evaluates <span class="extract"><span class="extract-syntax">a</span></span> then <span class="extract"><span class="extract-syntax">b</span></span> and returns the value of <span class="extract"><span class="extract-syntax">b</span></span>, discarding <span class="extract"><span class="extract-syntax">a</span></span>.
Now I6 does support the comma operator, and this makes a workable scheme,
right up to the point where some of the token values themselves include
invocations of functions, because I6's syntax analyser won't always
allow the serial comma to be mixed in the same expression with the
function argument comma, i.e., I6 is unable properly to handle expressions
like this one:
</p>
<pre class="displayed-code all-displayed-code code-font">
<span class="plain-syntax"> (</span><span class="identifier-syntax">a</span><span class="plain-syntax">(</span><span class="identifier-syntax">b</span><span class="plain-syntax">, </span><span class="identifier-syntax">c</span><span class="plain-syntax">), </span><span class="identifier-syntax">d</span><span class="plain-syntax">)</span>
</pre>
<p class="commentary">where the first comma constructs a list and the second is the operator.
(Many such expressions work fine, but not all.) That being so, the scheme
I actually use is:
</p>
<pre class="displayed-code all-displayed-code code-font">
<span class="plain-syntax"> (</span><span class="identifier-syntax">c</span><span class="plain-syntax">) + </span><span class="constant-syntax">0</span><span class="plain-syntax">*((</span><span class="identifier-syntax">b</span><span class="plain-syntax">) + (</span><span class="identifier-syntax">a</span><span class="plain-syntax">))</span>
</pre>
<p class="commentary">Because I6 evaluates the leaves in an expression tree right-to-left, not
left-to-right, the parameter assignments happen first, then the conditions,
then the result.
