6.7. Do...Loop Until Repetition Statement

The Do...Loop Until repetition statement is similar to the Do Until...Loop statement, except that the loop-termination condition is tested after the loop body is performed; therefore, the loop body executes at least once. When a Do...Loop Until terminates, execution continues with the statement after the Loop Until clause. Figure 6.13 uses a Do...Loop Until statement to print the numbers from 1 to 5.
