Language
Code written in VBA is compiled to a proprietary intermediate language called P-code (packed code), which the hosting applications (Access, Excel, Word, Outlook, and PowerPoint) store as a separate stream in COM Structured Storage files (e.g., .doc or .xls) independent of the document streams. The intermediate code is then executed by a virtual machine (hosted by the hosting application). Despite its resemblance to many old BASIC dialects (particularly Microsoft BASIC, from which it is indirectly derived), VBA is incompatible with any of them except Visual Basic, where source-code of VBA modules and classes can be directly imported, and which shares the same library and virtual machine. Compatibility ends with Visual Basic version 6; VBA is incompatible with Visual Basic .NET (VB.NET). VBA is proprietary to Microsoft and, apart from the COM interface, is not an open standard.

Famous quotes containing the word language:
““What may this mean? Language of Man pronounced
By tongue of brute, and human sense expressed!
The first at least of these I thought denied
To beasts, whom God on their creation-day
Created mute to all articulate sound;
The latter I demur, for in their looks
Much reason, and in their actions, oft appears.”
—John Milton (1608–1674)
“Which I wish to remark—
And my language is plain—
That for ways that are dark
And for tricks that are vain,
The heathen Chinee is peculiar:
Which the same I would rise to explain.”
—Bret Harte (1836–1902)
“The world does not speak. Only we do. The world can, once we have programmed ourselves with a language, cause us to hold beliefs. But it cannot propose a language for us to speak. Only other human beings can do that.”
—Richard Rorty (b. 1931)
