3.9 Do/LoopUntil Repetition Structure
The Do/LoopUntil structure is similar to the DoUntil/Loop structure, except that the loop-continuation condition is tested after the body of the loop is performed; therefore, the body of the loop executes at least once. When a Do/Loop Until terminates, execution continues with the statement after the LoopUntil clause. As an example of a Do/Loop Until repetition structure, once again consider the segment designed to find the first power of two larger than 1000:
Dim product As Integer = 1
Do
product = product * 2
Loop Until product >= 1000
