For Loop

 

The For Loop is perhaps the most useful of all the Loops. It runs a line or lines of code a set amount of times in any increment we set. The default increment is one. As you can see from below you must use a Variable of the Numeric type to set the amount of Loops it will perform.

 

 

Sub My_For()

Dim iMyNumber as Integer

 

For iMyNumber= 1 To 100

iMyNumber=1+iMyNumber

Range(“b2”).Value = iMyNumber

Next iMyNumber

 

End Sub

 

 

The other great part about the For Loop is we can increment by any Value we like. We do this by using the Step Key word and telling it the Step (or increment) to use. so we could use:

 

Sub My_For1()

Dim iMyNumber as Integer

Dim iMyNumber2 as Integer

 

For iMyNumber= 1 To 100 Step 2

iMyNumber2 =1+iMyNumber2

Next iMyNumber

 

Range(“b2”).Value = iMyNumber

 

End Sub

By doing this we will Loop through our code 51 times instead of 101 times, but the Variable iMyNumber will end up with a Value of 101.

 

We could also use the Step Key word to work backwards like below:

Sub My_For2()

Dim iMyNumber as Integer

Dim iMyNumber2 as Integer

 

For iMyNumber= 1000 To 1 Step -1

iMyNumber2 =1+iMyNumber2

Next iMyNumber

Range(“b2”).Value = iMyNumber

 

End Sub

 

This would mean that our Variable iMyNumber would end up with a Value of 0 (Zero).
