| <p><a name="index-line-comment-characters_002c-MMIX-1441"></a><a name="index-MMIX-line-comment-characters-1442"></a> |
| The characters ‘<samp><span class="samp">*</span></samp>’ and ‘<samp><span class="samp">#</span></samp>’ are line comment characters; each |
| start a comment at the beginning of a line, but only at the beginning of a |
| line. A ‘<samp><span class="samp">#</span></samp>’ prefixes a hexadecimal number if found elsewhere on a |
| line. If a ‘<samp><span class="samp">#</span></samp>’ appears at the start of a line the whole line is |
| treated as a comment, but the line can also act as 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>Two other characters, ‘<samp><span class="samp">%</span></samp>’ and ‘<samp><span class="samp">!</span></samp>’, each start a comment anywhere |
| on the line. Thus you can't use the ‘<samp><span class="samp">modulus</span></samp>’ and ‘<samp><span class="samp">not</span></samp>’ |
| operators in expressions normally associated with these two characters. |
| |
| <p>A ‘<samp><span class="samp">;</span></samp>’ is a line separator, treated as a new-line, so separate |
| instructions can be specified on a single line. |
