<p class="commentary firstcommentary"><a id="SP2_7" class="paragraph-anchor"></a><b>&#167;2.7. </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.

<p class="commentary firstcommentary"><a id="SP4" class="paragraph-anchor"></a><b>&#167;4. </b>This enables use of March 2009 extension to Glulx which optimises the speed
of Inform-compiled story files by moving the work of I6 veneer routines into
the interpreter itself. The empty function declaration here is misleading: its
actual contents are written out longhand during final code compilation to
Glulx, but not during e.g. final code compilation to C. This means that the
Inter tree doesn't need to refer to eldritch Glulx-only symbols like <span class="extract"><span class="extract-syntax">#g$self</span></span>
or implement assembly-language operations like <span class="extract"><span class="extract-syntax">@accelparam</span></span>. (See <a href="index.html" class="internal">final</a>.)
