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