5.7. Do Until...Loop Repetition Statement

Unlike the While and Do While...Loop repetition statements, the Do Until...Loop repetition statement 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 condition (known as the loop-termination condition) evaluates to false. The program of Fig. 5.7 finds the first power of 3 larger than 100 by using a Do Until...Loop repetition statement.
