Split Function
从字符串表达式返回一个子字符串数组。
语法：
Split (Text As String, delimiter, number)
返回值：
字符串
参数：
Text：任意字符串表达式。
delimiter（可选）：用于分隔文本的字符串，由一个或多个字符组成。默认的分隔字符是空格。
number（可选）：要返回的子字符串数目。
示例：
Dim a(3)
Sub main()
a(0) = "ABCDE"
a(1) = 42
a(2) = "MN"
a(3) = "X Y Z"
JStr = Join1()
Call Show(JStr, Split1(JStr))
JStr = Join2()
Call Show(JStr, Split1(JStr))
JStr = Join3()
Call Show(JStr, Split1(JStr))
End Sub
Function Join1()
Join1 = Join(a(), "abc")
End Function
Function Join2()
Join2 = Join(a(), ",")
End Function
Function Join3()
Join3 = Join(a())
End Function
Function Split1(aStr)
Split1 = Split(aStr, "D")
End Function
Sub Show(JoinStr, TheArray)
l = LBound(TheArray)
u = UBound(TheArray)
total$ = "=============================" + Chr$(13) + JoinStr + Chr$(13) + Chr$(13)
For i = l To u
total$ = total$ + TheArray(i) + Str(Len(TheArray(i))) + Chr$(13)
Next i
MsgBox total$
End Sub
