DevGuru WMLScript Statement: while



			STATEMENT: while while The while statement creates a loop that evaluates a expression to see if it is true or false, and if true, executes a block of statements and then repeats the loop, or if false, immediately exits the loop. The while statement will iterate the loop as long as the specified expression remains true. Therefore, if the expression never tests false, the loop will continue forever in what is called an "infinite loop." The block of statements executed by the while statement can be any legal WMLS code (including more while statements).
