Tried to search but didn't know how to phrase it. I've got some code that is essentially...

Private CurMajorStep as Integer = 0
Private CurMinorStep as Integer = 0

Public Sub PerformNextStep()
    Select Case iMajorStep
        Case 0
            ThingOne()
        Case 1
            ThingTwo()
        Case 2
            ThingThree()
        Case 3
            ThingFour()
        Case 4
            AnythingElse()
        Case 5
            Finish()
    End Select
End Sub

And then, in some of those, the CurMinorStep keeps track of the current state of that particular 'step'.

I hope that all makes sense.

The code is messy and I know it's going to be problematic to maintain. Can someone point me to a clean OO pattern to handle this?
