| <p>The presence of a ‘<samp>;</samp>’ on a line indicates the start of a comment |
| that extends to the end of the current line. If a ‘<samp>#</samp>’ or |
| ‘<samp>*</samp>’ appears as the first character of a line, the whole line is |
| treated as a comment. Note that if a line starts with a ‘<samp>#</samp>’ |
| character then it can also be a logical line number directive |
| (see <a href="Comments.html#Comments">Comments</a>) or a preprocessor control command |
| (see <a href="Preprocessing.html#Preprocessing">Preprocessing</a>). |
| </p> |

| <a name="index-statement-separator_002c-TIC6X"></a> |
| <a name="index-TIC6X-line-separator"></a> |
| <p>The ‘<samp>@</samp>’ character can be used instead of a newline to separate |
| statements. |
| </p> |
| <p>Instruction, register and functional unit names are case-insensitive. |
| <code>as</code> requires fully-specified functional unit names, |
| such as ‘<samp>.S1</samp>’, ‘<samp>.L1X</samp>’ or ‘<samp>.D1T2</samp>’, on all instructions |
| using a functional unit. |
| </p> |
| <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. |
