VBA - how to conditionally skip a for loop iteration

I have a for loop over an array. What I want to do is test for a certain condition in the loop and skip to the next iteration if true:

For i = LBound(Schedule, 1) To UBound(Schedule, 1)
    If (Schedule(i, 1) < ReferenceDate) Then
        PrevCouponIndex = i
        Continue   '*** THIS LINE DOESN'T COMPILE, nor does "Next"
    End If
    DF = Application.Run("SomeFunction"....)
    PV = PV + (DF * Coupon / CouponFrequency)
Next

I Know I can do:

 If (Schedule(i, 1) < ReferenceDate) Then Continue For

but I want to be able to record the last value of i in the PrevCouponIndex variable.

Any ideas?

Thanks

Solution 1:

VBA does not have a Continue or any other equivalent keyword to immediately jump to the next loop iteration. I would suggest a judicious use of Goto as a workaround, especially if this is just a contrived example and your real code is more complicated:

For i = LBound(Schedule, 1) To UBound(Schedule, 1)
    If (Schedule(i, 1) < ReferenceDate) Then
        PrevCouponIndex = i
        Goto NextIteration
    End If
    DF = Application.Run("SomeFunction"....)
    PV = PV + (DF * Coupon / CouponFrequency)
    '....'
    'a whole bunch of other code you are not showing us'
    '....'
    NextIteration:
Next

If that is really all of your code, though, @Brian is absolutely correct. Just put an Else clause in your If statement and be done with it.

Solution 2:

You can use a kind of continue by using a nested Do ... Loop While False:

'This sample will output 1 and 3 only

Dim i As Integer

For i = 1 To 3: Do

    If i = 2 Then Exit Do 'Exit Do is the Continue

    Debug.Print i

Loop While False: Next i

Solution 3:

Couldn't you just do something simple like this?

For i = LBound(Schedule, 1) To UBound(Schedule, 1)
  If (Schedule(i, 1) < ReferenceDate) Then
     PrevCouponIndex = i
  Else
     DF = Application.Run("SomeFunction"....)
     PV = PV + (DF * Coupon / CouponFrequency)
  End If
Next
