For Next lop ends on x +1

[werafa]

Hi,

I've noticed that

Private Sub testloop()
Dim myrow As Long

    For myrow = 1 To 10
    Next myrow

    Debug.Print myrow
End Sub

gives 11 as the output
Can anyone explain definitively why this is so? (I'd like to trust this enough to use it as a success/failure test)

thanks

the For..Next is analogous to

Do While myrow <= 10
Loop

it is incrementing loop (incrementint myrow on every Loop).
will only stop until myrow > 10.

thanks arneglp

so ...
myrow = myrow +1
if myrow < 11 then do the loop again
loop

[arnelgp]

mrow = 1
do until mrow > 10
mrow = mrow + 1
loop

The For / Next loop terminates when i > 10

Since the Next increments the loop variable i, it's last value = 10 + 1 = 11 and it doesn't loop any more

What are you really trying to do that you want to make this a success/failure test?

If you don't trust something or don't know if something is right or not, make a test run.
have an empty Sheet and run the code you're wondering about.

Sub What_Is_The_Outcome_A()
Dim i As Long
    For i = 1 To 10
        Cells(i, 3).Value = i
    Next i
End Sub

Sub What_Is_The_Outcome_B()
Dim i As Long
i = 1
    Do While i <= 10
        Cells(i, 5).Value = i
        i = i + 1
    Loop
End Sub

That will give you a visual of the outcome.
Pretty soon it will be second nature.
