<a name="index-line-comment-character_002c-Z80"></a>
|
|
<a name="index-Z80-line-comment-character"></a>
|
|
<p>The semicolon ‘<samp>;</samp>’ is the line comment character;
|
|
</p>
|
|
<p>If a ‘<samp>#</samp>’ appears as the first character of a line then the whole
|
|
line is treated as a comment, but in this case the line could 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-line-separator_002c-Z80"></a>
|
|
<a name="index-statement-separator_002c-Z80"></a>
|
|
<a name="index-Z80-line-separator"></a>
|
|
<p>The Z80 assembler does not support a line separator character.
|
|
</p>

<a name="index-location-counter_002c-Z80"></a>
|
|
<a name="index-hexadecimal-prefix_002c-Z80"></a>
|
|
<a name="index-Z80-_0024"></a>
|
|
<p>The dollar sign ‘<samp>$</samp>’ can be used as a prefix for hexadecimal numbers
|
|
and as a symbol denoting the current location counter.
|
|
</p>
|
|
<a name="index-character-escapes_002c-Z80"></a>
|
|
<a name="index-Z80_002c-_005c"></a>
|
|
<p>A backslash ‘<samp>\</samp>’ is an ordinary character for the Z80 assembler.
|
|
</p>
|
|
<a name="index-character-constant_002c-Z80"></a>
|
|
<a name="index-single-quote_002c-Z80"></a>
|
|
<a name="index-Z80-_0027"></a>
|
|
<p>The single quote ‘<samp>'</samp>’ must be followed by a closing quote. If there
|
|
is one character in between, it is a character constant, otherwise it is
|
|
a string constant.
