+<center><h1>The DO keyword.</h1></center>
+<hr>
+The <b>do</b> keyword performs a simular function to
+<a href="while.html">while</a>. Basicaly, it repeats a block of statements.
+Here is an example of the syntax:
+<pre>
+ main()
+ {
+ int i=5;
+
+ do
+ {
+ printf(" i is %d\n", i);
+ }
+ while(--i);
+ }
+
+</pre>
+
+The program result will look like this:
+<pre>
+ i is 5
+ i is 4
+ i is 3
+ i is 2
+ i is 1
+</pre>
+The main difference between <b>do</b> and <a href=while.html>while</a> is
+the time that expression is evaluated.
+<ul>
+<li><b>do</b> performs the first test AFTER the first iteration.
+<li><b>while</b> performs the first test BEFORE the first iteration.
+</ul>
