| <p><a name="index-line-comment-character_002c-TIC6X-1823"></a><a name="index-TIC6X-line-comment-character-1824"></a>The presence of a ‘<samp><span class="samp">;</span></samp>’ on a line indicates the start of a comment |
| that extends to the end of the current line. If a ‘<samp><span class="samp">#</span></samp>’ or |
| ‘<samp><span class="samp">*</span></samp>’ 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 ‘<samp><span class="samp">@</span></samp>’ 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 ‘<samp><span class="samp">.S1</span></samp>’, ‘<samp><span class="samp">.L1X</span></samp>’ or ‘<samp><span class="samp">.D1T2</span></samp>’, 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. |
