The registers are referred to with the letters assigned to them by

						|
Zilog. In addition <span class="command">as</span> recognizes <span class="samp">ixl</span> and
 | 
						|
<span class="samp">ixh</span> as the least and most significant octet in <span class="samp">ix</span>, and
 | 
						|
similarly <span class="samp">iyl</span> and  <span class="samp">iyh</span> as parts of <span class="samp">iy</span>.
