WHILE Loops
<![CDATA[
WHILE loops check the condition and execute a set of commands.
The loop is repeated until the loop is exited.
A WHILE loop is exactly equivalent to a regular loop with an EXIT WHEN as the first statement.
The condition is checked before the code in the loop is executed.
If the condition is false, the code in the loop will never be executed.
WHILE loop makes your code a little easier to read than with a normal loop.
