      ' Do Until: The statement block is repeated as long as the condition is false
         statements
         [Exit Do]
         statements
      Loop

      Do
         statements
         [Exit Do]
         statements
      ' Loop While: The statement block repeats as long as the condition is true
      ' Loop Until: The statement block repeats until the condition is true
      Loop {While | Until} condition = True
