<p class="commentary firstcommentary"><a id="SP7" class="paragraph-anchor"></a><b>&#167;7. PLMs. </b>At some point PLM stood for something, but what it was is now forgotten &mdash;
perhaps "parse linked matter"? &mdash; so it is now a nonsense-word pronounced
"plum". This is a marker attached to a splat which can indicate which Inform
6-syntax directive the splat contains (if any).
</p>
<p class="commentary"><span class="extract"><span class="extract-syntax">WHITESPACE_PLM</span></span> should be used only if the splat contains nothing but white
space. <span class="extract"><span class="extract-syntax">MYSTERY_PLM</span></span> should be used if its contents are of an unknown syntax.
The other names here are taken from their corresponding I6 directives.
