<p><a name="index-single-character-constant-164"></a><a name="index-character_002c-single-165"></a><a name="index-constant_002c-single-character-166"></a>A single character may be written as a single quote immediately
followed by that character. The same escapes apply to characters as
to strings. So if you want to write the character backslash, you
must write <kbd>'\\</kbd> where the first <code>\</code> escapes the second
<code>\</code>. As you can see, the quote is an acute accent, not a
grave accent. A newline
immediately following an acute accent is taken as a literal character
and does not count as the end of a statement. The value of a character
constant in a numeric expression is the machine's byte-wide code for
that character. <samp><span class="command">as</span></samp> assumes your character code is ASCII:
<kbd>'A</kbd> means 65, <kbd>'B</kbd> means 66, and so on.
