The "pattern" was introduced in an earlier Daily WTF article. The basic idea is that you have a for loop with a case inside of it that selects based on the for loop index variable, e.g.:

For Icnt = 0 To 5 Select Case Icnt Case 0 DoStuff() Case 1 DoOtherStuff() Case 2 DoMoreStuff() Case 3 DoDifferentStuff() Case 4 DoYetMoreStuff() Case 5 DoFinalStuff() End Select Next

Assuming the index variable can't be changed inside the loop, (which is not always true, depending on which language you're using,) a bit of analysis demonstrates that the execution is exactly the same as if you removed the for and the case entirely and all the case blocks were simply executed sequentially.:

DoStuff() DoOtherStuff() DoMoreStuff() DoDifferentStuff() DoYetMoreStuff() DoFinalStuff()
