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:
“I shall christen this style the Mandarin, since it is beloved by literary pundits, by those who would make the written word as unlike as possible to the spoken one. It is the style of all those writers whose tendency is to make their language convey more than they mean or more than they feel, it is the style of most artists and all humbugs.”
—Cyril Connolly (1903–1974)
“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)
“Had Dr. Johnson written his own life, in conformity with the opinion which he has given, that every man’s life may be best written by himself; had he employed in the preservation of his own history, that clearness of narration and elegance of language in which he has embalmed so many eminent persons, the world would probably have had the most perfect example of biography that was ever exhibited.”
—James Boswell (1740–95)
