<h4 class="subsection">Constants</h4>



   <p>All constants are integers.



   <p>As in C, the linker considers an integer beginning with <code>0</code> to be

octal, and an integer beginning with <code>0x</code> or <code>0X</code> to be

hexadecimal.  The linker considers other integers to be decimal.



   <p>In addition, you can use the suffixes <code>K</code> and <code>M</code> to scale a

constant by

respectively. For example, the following all refer to the same quantity:

<pre class="smallexample">       _fourk_1 = 4K;

       _fourk_2 = 4096;

       _fourk_3 = 0x1000;

     </pre>
