Software developers using C++, .NET, or Delphi can license the VBA Core to add macro capabilities to their own products. This is how applications like CorelDRAW and AutoCAD gained VBA support.

Once installed, you can harness capabilities unavailable in standard VBA:

' Save as CoreTest.vba
Sub ExclusiveTask()
    Dim fs As Object
    Set fs = CreateObject("Scripting.FileSystemObject")
    Dim log As Object
    Set log = fs.CreateTextFile("C:\VBA_Exclusive.log", True)
    log.WriteLine "VBA Core Exclusive is running at " & Now
    log.Close
End Sub

Run from CMD:

C:\Windows\System32\cscript.exe "CoreTest.vba" //E:VBScript
