How to use MacScript function in VBA?

`MacScript` is a function in VBA (Visual Basic for Applications) that allows you to run AppleScript code from within a VBA macro in Microsoft Excel for Mac. By using this function, you can perform tasks on your Mac that would otherwise be outside the capabilities of VBA, essentially extending your VBA script’s functionality to control other applications on macOS.

Since Microsoft has been updating Excel for Mac, the `MacScript` function was deprecated in newer versions. If you’re using Excel 2016 or later for Mac, you won’t be able to use `MacScript` directly as it used to be in older versions. Instead, you might need to use AppleScriptTask to call an AppleScript script stored on the disk.

However, if you are indeed working with an older version of Excel for Mac that supports the `MacScript` function, you can use it like this:

Open Microsoft Excel for Mac.
Press `Alt` + `F11` to open the VBA Editor.
Insert a new module or use an existing one in the VBA project.
Write a VBA macro that includes the `MacScript` function, using AppleScript syntax for the script part.

Here’s an example VBA macro using `MacScript` (in older versions of Excel for Mac):

Sub RunAppleScript()
    Dim script As String
    Dim result As String

    ' AppleScript command to say "Hello World"
    script = "say ""Hello, World"""

    ' Run the AppleScript command via MacScript
    result = MacScript(script)

    ' Optionally, use the result
    MsgBox result
End Sub

In the above example, the `MacScript` function is used to execute a simple AppleScript command that instructs the Mac to audibly say “Hello, World”.

If you are working with Excel 2016 or later for Mac and need to execute AppleScript, you need to save your AppleScript on disk and call it using `AppleScriptTask` as outlined below:

on run argv
    say "Hello, World"
    return "Done"
end run

Sub RunAppleScriptTask()
    Dim result As String
    result = AppleScriptTask("HelloWorld.scpt", "run", "")
    MsgBox result
End Sub

Write an AppleScript script and save it with the `scpt` extension in the `~/Library/Application Scripts/com.microsoft.Excel` folder. For example, create a file named `HelloWorld.scpt`.
Your AppleScript could look like this:
From your Excel VBA module, use the `AppleScriptTask` function to call your AppleScript file.

Remember that `AppleScriptTask` is the approach for automation scripts in newer Excel for Mac versions where direct inline AppleScript execution via `MacScript` is no longer supported.
