Sub Test1()
    Dim a As Integer
    For a = 1 To 3 Step 1 'STEP POSITIVE ONE
    Next
    Debug.Print a
End Sub

收益率为4,如预期.

Sub Test2()
    Dim a As Integer
    For a = 1 To 3 Step -1 'STEP NEGATIVE ONE
    Next
    Debug.Print a
End Sub

为什么踩到"外部"循环会导致1？

为什么VBA步入Test1的界限,但是当它对于Test2的超出部分时停止踩踏？

编辑:除了上述,运行For a = 1 To 1 Step 1结果为2,For a = 1 To 1 Step -1结果为0.

For a = 1 To 2 Step 1结果为3,但For a = 1 To …
