<p class="commentary firstcommentary"><a id="SP8"></a><b>&#167;8. </b>The stock inventory can also be used to make references. Using the stock
ID number (plus 1) as the reference ID of a linguistic constant reference,
we can effectively have a single <span class="extract"><span class="extract-syntax">int</span></span> value refer to a stock item together
with any combination of gender, person, number, mood, case, tense, and sense.
The "plus 1" is so that a reference ID of zeri can mean "no item".
