3.7 DoUntil/Loop Repetition Structure
Unlike the While and DoWhile/Loop repetition structures, the DoUntil/Loop repetition structure tests a condition for falsity for repetition to continue. Statements in the body of a Do Until/Loop are executed repeatedly as long as the loop-continuation test evaluates to false. As an example of a DoUntil/Loop repetition structure, once again consider the segment designed to find the first power of two larger than 1000:
Dim product As Integer = 2
Do Until product >= 1000
product = product * 2
Loop
