在excle中怎样执行主过程和子过程

1、打开excle软件，进入VBA的编程界面，打开其中一个模块进行编辑，事先做好了几个子过程和函数，GetUsername，GetFirst，GetLast，DisplayLastFirst

2、接着是设置主过程，也就是程序执行的入口，命名为username

3、然后定义变量Dim full As String, first As String, last As String

4、接着是调用子过程GetUsername。Call GetUsername(full)

5、再调用GetFirst，获得名字的第一个。first = GetFirst(full)

6、调用GetLast，获得名字的最后一个。last = GetLast(full)

7、最后调用DisplayLastFirst，用来输出名字。Call DisplayLastFirst(first, last)完整代码如下：Sub UserName() Dim full As String, first As String, last As String Call GetUsername(full) first = GetFirst(full) last = GetLast(full) Call DisplayLastFirst(first, last) End SubSub GetUsername(fullname As String) fullname = InputBox("请输入你的第一个名字和最后一个名字")End SubFunction GetFirst(fullname As String) Dim space As Integer space = InStr(fullname, " ") GetFirst = Left(fullname, space - 1)End FunctionFunction GetLast(fullname As String) Dim space As Integer space = InStr(fullname, " ") GetLast = Right(fullname, Len(fullname) - space) End FunctionSub DisplayLastFirst(first, last) MsgBox first & "," & lastEnd Sub

8、最后运行这个程序。
