The For...Next loop structure is best when the number of repetitions needed for a set of instructions is known ahead of time. It allows for the initialization of a counter variable, a condition to continue looping based on that variable, and an increment/decrement statement to modify the variable each time through the loop. This makes it easy to control the exact number of repetitions needed.
