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:
“Repeat thy song, till the familiar lines
Are footpaths for the thought of Italy!
Thy flame is blown abroad from all the heights,
Through all the nations, and a sound is heard,
As of a mighty wind, and men devout,
Strangers of Rome, and the new proselytes,
In their own language hear thy wondrous word,
And many are amazed and many doubt.”
—Henry Wadsworth Longfellow (1809–1882)
“Our goal as a parent is to give life to our children’s learning—to instruct, to teach, to help them develop self-discipline—an ordering of the self from the inside, not imposition from the outside. Any technique that does not give life to a child’s learning and leave a child’s dignity intact cannot be called discipline—it is punishment, no matter what language it is clothed in.”
—Barbara Coloroso (20th century)
“After all, when you come right down to it, how many people speak the same language even when they speak the same language?”
—Russell Hoban (b. 1925)
