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:
“Poetry is the universal language which the heart holds with nature and itself. He who has a contempt for poetry, cannot have much respect for himself, or for anything else.”
—William Hazlitt (1778–1830)
“Syntax is the study of the principles and processes by which sentences are constructed in particular languages. Syntactic investigation of a given language has as its goal the construction of a grammar that can be viewed as a device of some sort for producing the sentences of the language under analysis.”
—Noam Chomsky (b. 1928)
“Our language has wisely sensed these two sides of man’s being alone. It has created the word “loneliness” to express the pain of being alone. And it has created the word “solitude” to express the glory of being alone. Although, in daily life, we do not always distinguish these words, we should do so consistently and thus deepen our understanding of our human predicament.”
—Paul Tillich (1886–1965)
