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:
“Man acts as though he were the shaper and master of language, while in fact language remains the master of man.”
—Martin Heidegger (1889–1976)
“Because language is the carrier of ideas, it is easy to believe that it should be very little else than such a carrier.”
—Louise Bogan (1897–1970)
“I invented the colors of the vowels!—A black, E white, I red, O blue, U green—I made rules for the form and movement of each consonant, and, and with instinctive rhythms, I flattered myself that I had created a poetic language accessible, some day, to all the senses.”
—Arthur Rimbaud (1854–1891)
