<p class="commentary firstcommentary"><a id="SP1_5" class="paragraph-anchor"></a><b>&#167;1.5. </b>Finally, a function used when printing values of the <span class="extract"><span class="extract-syntax">K_response</span></span> kind;
the main compiler created this as a mostly empty function with two local
variables &mdash; <span class="extract"><span class="extract-syntax">R</span></span>, the ID for the response we should print, and <span class="extract"><span class="extract-syntax">RPR</span></span>, the
address of a function for printing rule names.
</p>
<p class="commentary">This is in effect a big switch statement, so it's not fast; but being a print
function it doesn't need to be.
</p>
<p class="commentary">The only reason this is a function at all, rather than using far more
efficient array lookups, is that we have to guard accessible memory space on
the Z-machine, where such an array could consume over 1K, but where memory for
code is less limited.
