These are Keil proprietary keyword extensions to support the specifics of the 8051 architecture.&lt;br /&gt;
&lt;br /&gt;
It sounds like you need to read the uVision &lt;i&gt;Getting Started&lt;/i&gt; Guide - &lt;b&gt;and work through the example projects in it&lt;/b&gt;. This will give you a proper introduction to the tools, how they work, and how to use them - rather than just blindly jumping-in at the deep end.&lt;br /&gt;
&lt;br /&gt;
You probably also need to do some basic reading on the 8051 architecture - the following are commonly referred to as the &amp;quot;bible&amp;quot; for the 8051:&lt;br /&gt;
