<p class="inwebparagraph"><a id="SP2"></a><b>§2. </b>In two different contexts (action patterns and specifications) we
|
|
will need a represention for periods of time. We measure time in two
|
|
units: "times", as in something having been true four times in the
|
|
past; and "turns", as in something having been true for five turns
|
|
now. We will also need to keep track of four tenses when discussing
|
|
time periods, and also whether we mean "three or more" (say) or
|
|
"less than seven" turns or times. We represent this using the
|
|
relevant I6 comparison operator: for instance a length of 5 and
|
|
an operator <code class="display"><span class="extract">>=</span></code> denotes "five or more". Lastly, we can denote a
|
|
closed interval of time as well, by setting <code class="display"><span class="extract">until</span></code> to the upper
|
|
end.
