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:
“Language is an archeological vehicle ... the language we speak is a whole palimpsest of human effort and history.”
—Russell Hoban (b. 1925)
“Please stop using the word “Negro.”... We are the only human beings in the world with fifty-seven variety of complexions who are classed together as a single racial unit. Therefore, we are really truly colored people, and that is the only name in the English language which accurately describes us.”
—Mary Church Terrell (1863–1954)
“There is no such thing as an ugly language. Today I hear every language as if it were the only one, and when I hear of one that is dying, it overwhelms me as though it were the death of the earth.”
—Elias Canetti (b. 1905)
