'●用Function当成子程序的一个好处，就是Function本身可以传回一个值到上一层呼叫的子程序里，但问题来了，若为了工作上的需要，想一次传回一个以上的值，那该怎么办？Private Sub Command1_Click()MyReturn 5,6End SubPrivate Function MyReturn(X,Y) As LongA = X + YB = X - YC = X * YD = X / Y'想传回A、B、C、D四个数值回去，怎么写？End Function'●这是一个基本的观念问题，子程序与子程序间的传值有ByVal与ByRef两种，ByVal是两个子程序间的传值放在不同的内存位置，而预设的ByRef则是将传值放在同一个内存位置上，故这一点可以拿来利用，可将上式改写成：Private Sub Command1_Click()MyReturn 5,6,Ans1,Ans2,Ans3,Ans4MsgBox "答案分别是" & Ans1 & "," & Ans2 & "," & Ans3 & "," & Ans4End SubPrivate Function MyReturn(X,Y,A,B,C,D) As LongA = X + YB = X - YC = X * YD = X / YEnd Function'●或是把资料作成Variant型态数组传回：Private Sub Command1_Click()Ans = MyReturn(5,6)MsgBox "答案分别是" & Ans(0) & "," & Ans(1) & "," & Ans(2) & "," & Ans(3)End SubPrivate Function MyReturn(X,Y) As VariantMyReturn = Array(X + Y,X - Y,X * Y,X / Y)End Function
