如果存在如下过程： Private Function Fun(a()As Integer) Dim First As Integer，Last As Integer，i As Integer First=LBound(a) Last=LBound(a) Max=a(First) For i=First To Last If a(i)＞Max Then Max=a(i) Next Fun=Max End Function 在窗体上添加一个命令按钮，然后编写如下事件过程： Private Sub Command1_Click() ReDim in(1 To 4)As Integer m(1=20:m(2)=30:m(3)+50:m(4)=100 c=Fun(m) Print c End Sub 单击命令按钮，其输出结果为______。
