<h3>Character Constants as Integer Values</h3>
<p>(ISO C, §6.4.4.4) The C compiler lets you use string literals containing 2 to 8 characters to denote 32-bit or 64-bit integer values. Table 2.2 shows examples.</p>
<p>Table 2.2 Integer Values as Character String Constants</p>
<table width="73%" border="0" cellpadding="2" cellspacing="0">
<tr>
<th width="33%" scope="col">Character constant</th>
<th width="67%" scope="col">Equivalent hexadecimal integer value</th>
</tr>
<tr>
<td class="code">'ABCDEFGH'</td>
<td><span class="code">0x4142434445464748</span> (64-bit value)</td>
</tr>
<tr>
<td class="code">'ABCDE'</td>
<td><span class="code">0x0000000041424344</span> (64-bit value)</td>
</tr>
<tr>
<td class="code">'ABCD'</td>
<td><span class="code">0x41424344</span> (32-bit value)</td>
</tr>
<tr>
<td class="code">'ABC'</td>
<td><span class="code">0x00414243</span> (32-bit value)</td>
</tr>
<tr>
<td class="code">'AB'</td>
<td><span class="code">0x00004142</span> (32-bit value)</td>
</tr>

<p>You cannot disable this extension, and it has no corresponding pragma or setting in any panel.</p>
<p class="note"><strong>NOTE</strong> This feature differs from using multibyte character sets, where a single character requires a data type larger than 1 byte. See <a href="c_multibyte_support.htm">Multibyte and Unicode Support</a> for information on using character sets with more than 256 characters (such as Kanji).<br />
