<p><a name="index-line-comment-character_002c-TIC6X-1823"></a><a name="index-TIC6X-line-comment-character-1824"></a>The presence of a &lsquo;<samp><span class="samp">;</span></samp>&rsquo; on a line indicates the start of a comment
that extends to the end of the current line.  If a &lsquo;<samp><span class="samp">#</span></samp>&rsquo; or
&lsquo;<samp><span class="samp">*</span></samp>&rsquo; appears as the first character of a line, the whole line is
treated as a comment.

   <p><a name="index-line-separator_002c-TIC6X-1825"></a><a name="index-statement-separator_002c-TIC6X-1826"></a><a name="index-TIC6X-line-separator-1827"></a>The &lsquo;<samp><span class="samp">@</span></samp>&rsquo; character can be used instead of a newline to separate
statements.

   <p>Instruction, register and functional unit names are case-insensitive. 
<samp><span class="command">as</span></samp> requires fully-specified functional unit names,
such as &lsquo;<samp><span class="samp">.S1</span></samp>&rsquo;, &lsquo;<samp><span class="samp">.L1X</span></samp>&rsquo; or &lsquo;<samp><span class="samp">.D1T2</span></samp>&rsquo;, on all instructions
using a functional unit.

   <p>For some instructions, there may be syntactic ambiguity between
register or functional unit names and the names of labels or other
symbols.  To avoid this, enclose the ambiguous symbol name in
parentheses; register and functional unit names may not be enclosed in
parentheses.
