    							For i = 1 To 100 or For i = 1 To 100 Step 1

  2. Vary the control variable from 100 to 1 in increments of -1 (decrements of 1).

    							For i = 100 To 1 Step -1

  3. Vary the control variable from 7 to 77 in increments of 7.

    							For i = 7 To 77 Step 7

  4. Vary the control variable from 20 to 2 in increments of -2 (decrements of 2).

    							For i = 20 To 2 Step -2

  5. Vary the control variable over the sequence of the following values: 2, 5, 8, 11, 14, 17, 20.

    							For i = 2 To 20 Step 3
