主题：内部函数执行后的结果，如何进行调用或弹出

'''
Dim Multi As String = Args(0)

Dim b As Integer
Dim Values() As String
If Multi > "" AndAlso Multi.Contains("、") Then
    Values = Multi.split("、")
    b=Values.count
Else If Multi > "" AndAlso Multi.Contains("，") Then
    Values = Multi.split("，")
    b=Values.count
End If
Return b

Functions.Execute("字符串统计","1,2,3,4")

如何弹出4这个结果呢？
