You can use a counter variable that increases or decreases with each repetition of the loop, like this: For i = 1 to 10
some code
Next The For statement specifies the counter variable i and its start and end values. The Next statement
increases i by 1. Using the Step keyword, you can increase or decrease the counter variable by the value you specify. For i = 2 To 10 Step 2
some code
Next In the example above, i is increased by 2 each time the loop repeats. When the loop is finished, total is the
sum of 2, 4, 6, 8, and 10. To decrease the counter variable, you use a negative Step value. You must specify an end value that is
less than the start value. For i = 10 To 2 Step -2
some code
Next In the example above, i is decreased by 2 each time the loop repeats. When the loop is finished, total is the
sum of 10, 8, 6, 4, and 2. Exiting a For...Next You can exit a For...Next statement with the Exit For keyword. For Each...Next A For Each...Next loop repeats a block of code for each item in a collection, or for each element of an array. The For Each...Next statement looks almost identical to the For...Next statement. The difference is that you
do not have to specify the number of items you want to loop through. dim names(3)
names(0) = "Tove"
names(1) = "Jani"
names(2) = "Hege"

For Each item in names
