Question

Private Sub Form_Click( ) Dim x As Integer,y As Integer,z As

Answer 1

Call Procl(x,x,z) 这是个调用过程的语句,他把x,y,z的值传递给procl这个过程,在这个过程中执行相应的操作.Call Procl(x,x,z) 应该是Call Procl(x,y,z)吧,你打错了哈 下面给你一个列子：

判断三个数中最大的那个数：

Private Sub Form_Click()

Dim x As Integer,y As Integer,z As Integer

x = 1:y = 2:z = 3

Call procl(x,y,z)

End Sub

Public Sub procl(a%,b%,c%)

Dim i,j,teap As Integer

If a > b Then teap = a Else teap = b

If teap > c Then teap = teap Else teap = c

Print "输出最大值：" & teap

End Sub

自己看哈,
