CHAPTER 20 — Further about the FOR Statement

The previous chapter introduced the FOR statement. The FOR statement is an easy way to implement counting loops. A counting loop uses a counter which begins at a starting value and counts its way to a final value. This chapter will discuss a few further details of the FOR statement and present some additional examples.

Chapter Topics:

• Not all loops are counting loops
• Using STEP to count up or down by different amounts
• How to determine when a FOR loop will finish
• Nesting an IF-THEN-ELSE inside a FOR loop
• Nested FOR loops
