<p class="commentary firstcommentary"><a id="SP2" class="paragraph-anchor"></a><b>&#167;2. Phases III and IV: Sort and Compile Grammar. </b>At this highest level phases III and IV are intermingled, in that Phase III
always precedes Phase IV for any given list of grammar lines, but each CG
goes through both Phase III and IV before the next begins Phase III. So it
would not be appropriate to print banners like "Phase III begins here"
in the debugging log.
</p>
<p class="commentary">Finally, though, some substantive work to do: because it is the CG which
records the purpose of the grammar in question, we must compile a suitable
I6 context for the grammar to appear within.
</p>
<p class="commentary">Four of the five kinds of CG are compiled by the routine below: the fifth
kind is compiled in "Tokens Parsing Values", in response to different
<span class="extract"><span class="extract-syntax">.i6t</span></span> commands, because the token routines are needed at a different position
in the final I6 output.
</p>
<p class="commentary">Sequence is important here: in particular the GPRs must exist before the
<span class="extract"><span class="extract-syntax">Verb</span></span> directives, because otherwise I6 will throw not-declared-yet errors.

<p class="commentary firstcommentary"><a id="SP7" class="paragraph-anchor"></a><b>&#167;7. </b>The following function unites, so far as possible, the different forms of
CG by compiling each of them as a sandwich: top slice, filling, bottom slice.
</p>
<p class="commentary">The interesting case is of a CG representing names for an object: the
name-behaviour needs to be inherited from the object's kind, and so on up
the kinds hierarchy, but this is a case where I7's kind hierarchy does not
agree with I6's class hierarchy. I6 has no (nice) way to inherit <span class="extract"><span class="extract-syntax">parse_name</span></span>
behaviour from a class to an instance. So we will simply pile up extra
fillings into the sandwich. The order of these is important: by getting
in first, grammar for the instance takes priority; its immediate kind has
next priority, and so on up the hierarchy.
