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:
“We have tried so hard to adulterate our hearts, and have so greatly abused the microscope to study the hideous excrescences and shameful warts which cover them and which we take pleasure in magnifying, that it is impossible for us to speak the language of other men.”
—Charles Baudelaire (1821–1867)
“In a language known to us, we have substituted the opacity of the sounds with the transparence of the ideas. But a language we do not know is a closed place in which the one we love can deceive us, making us, locked outside and convulsed in our impotence, incapable of seeing or preventing anything.”
—Marcel Proust (1871–1922)
“To write or even speak English is not a science but an art. There are no reliable words.... Whoever writes English is involved in a struggle that never lets up even for a sentence. He is struggling against vagueness, against obscurity, against the lure of the decorative adjective, against the encroachment of Latin and Greek, and, above all, against the worn-out phrases and dead metaphors with which the language is cluttered up.”
—George Orwell (1903–1950)
