+<h2>Full example</h2>
+<pre><code>+++++ +++               Set Cell #0 to 8
+[
+    >++++               Add 4 to Cell #1; this will always set Cell #1 to 4
+    [                   as the cell will be cleared by the loop
+        >++             Add 2 to Cell #2
+        >+++            Add 3 to Cell #3
+        >+++            Add 3 to Cell #4
+        >+              Add 1 to Cell #5
+        <<<<-           Decrement the loop counter in Cell #1
+    ]                   Loop till Cell #1 is zero; number of iterations is 4
+    >+                  Add 1 to Cell #2
+    >+                  Add 1 to Cell #3
+    >-                  Subtract 1 from Cell #4
+    >>+                 Add 1 to Cell #6
+    [<]                 Move back to the first zero cell you find; this will
+                        be Cell #1 which was cleared by the previous loop
+    <-                  Decrement the loop Counter in Cell #0
+]                       Loop till Cell #0 is zero; number of iterations is 8
+
+The result of this is:
+Cell No :   0   1   2   3   4   5   6
+Contents:   0   0  72 104  88  32   8
+Pointer :   ^
+
+>>.                     Cell #2 has value 72 which is 'H'
+>---.                   Subtract 3 from Cell #3 to get 101 which is 'e'
++++++++..+++.           Likewise for 'llo' from Cell #3
+>>.                     Cell #5 is 32 for the space
+<-.                     Subtract 1 from Cell #4 for 87 to give a 'W'
+<.                      Cell #3 was set to 'o' from the end of 'Hello'
++++.------.--------.    Cell #3 for 'rl' and 'd'
+>>+.                    Add 1 to Cell #5 gives us an exclamation point
+>++.                    And finally a newline from Cell #6</code></pre>
