<h4 class="subsection">9.23.3 Syntax</h4>
<p>The assembly syntax is supposed to be upward compatible with that
described in Sections 1.3 and 1.4 of <span class="samp">The Art of Computer
Programming, Volume 1</span>. Draft versions of those chapters as well as other
MMIX information is located at
<a name="mmixsite"></a><a href="http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html">http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html</a>.
Most code examples from the mmixal package located there should work
unmodified when assembled and linked as single files, with a few
noteworthy exceptions (see <a href="MMIX_002dmmixal.html#MMIX_002dmmixal">MMIX-mmixal</a>).
<p>Before an instruction is emitted, the current location is aligned to the
next four-byte boundary. If a label is defined at the beginning of the
line, its value will be the aligned value.
<p>In addition to the traditional hex-prefix <span class="samp">0x</span>, a hexadecimal number
can also be specified by the prefix character <span class="samp">#</span>.
<p>After all operands to an MMIX instruction or directive have been
specified, the rest of the line is ignored, treated as a comment.
