<p>
Puts the value of the instrument's internal <span class="quote">“<span class="quote">tie-in</span>”</span> flag into the named i-rate variable. Assigns 1 if this note has been <span class="quote">“<span class="quote">tied</span>”</span> onto a previously held note (see <a class="link" href="i.html" title="i Statement (Instrument or Note Statement)"><em class="citetitle">i statement</em></a>); assigns 0 if no tie actually took place.
