<p class="commentary firstcommentary"><a id="SP5_1" class="paragraph-anchor"></a><b>§5.1. </b>Note that numerical comparisons are handled by two methods. Verbally, they are
|
|
prepositions: "less than", for instance, is combined with "to be", giving us
|
|
"A is less than B" and similar forms. These wordy forms are therefore defined
|
|
as prepositional usages and created as such in Basic Inform. But we also
|
|
permit the use of the familiar mathematical symbols <span class="extract"><span class="extract-syntax"><</span></span>, <span class="extract"><span class="extract-syntax">></span></span>, <span class="extract"><span class="extract-syntax"><=</span></span> and <span class="extract"><span class="extract-syntax">>=</span></span>.
|
|
Inform treats these as "operator verbs" without tense, so registers them as
|
|
verb usages, but without the full conjugation given to a conventional verb;
|
|
and they are also excluded from the lexicon in the Phrasebook index, being
|
|
notation rather than words. (This is why the variable <span class="extract"><span class="extract-syntax">current_main_verb</span></span> is
|
|
cleared.)

<p class="commentary firstcommentary"><a id="SP5_2_2_1_1" class="paragraph-anchor"></a><b>§5.2.2.1.1. </b>The syntax allowing parts of speech to be given in brackets goes back to
|
|
the very early days of Inform, and is now deprecated. It generalises badly to
|
|
other languages, and doesn't even work perfectly for English.
|
|
</p>
|
|
|
|
<p class="commentary">The problem is that the source text is allowed to give only a selection of the
|
|
parts of the verb, and Inform has to guess which parts. So how does it
|
|
distinguish "X is suspected" from "X is suspecting"? It needs to know which is
|
|
the present participle, and it does this by looking for an -ing ending on
|
|
either the first or last word.
|
|
</p>
|
|
|
|
<p class="commentary">We read the parts of speech as a comma-separated list of individual parts
|
|
(but we don't allow "and" or "or" to divide this list: only commas).
|
|
</p>
|
|
|
|
<p class="commentary">At the end, if no present plural is supplied, we may as well use the
|
|
infinitive for that — the two are the same in most regular English verbs
|
|
("to sleep", "they sleep") even if not irregular ones ("to be", "they are").
