VBA 函数调用中括号的使用有哪些规则

VBA（Visual Basic for Applications）是一种用于宏编程的语言，常用于在Microsoft Office应用程序中自动化任务。在VBA中，函数调用是一种常见的操作，而使用括号来调用函数是一种基本的语法规则。本文将介绍VBA函数调用中括号的使用规则，并提供相应的案例代码。

MsgBox "Hello, World!"

Dim ws As Worksheet
Set ws = Worksheets("Sheet1")

Dim rng As Range
Set rng = Range("A1:B5")

Dim position As Integer
position = InStr(InStr(1, "Hello, World!", "o"), "o")

Sub Test()
    MsgBox "Hello, World!"
    
    Dim ws As Worksheet
    Set ws = Worksheets("Sheet1")
    
    Dim rng As Range
    Set rng = Range("A1:B5")
    
    Dim position As Integer
    position = InStr(InStr(1, "Hello, World!", "o"), "o")
End Sub
