OpenOffice Basic

OpenOffice Basic is a dialect of the BASIC programming language that grew out of the StarOffice office suite and was carried forward by OpenOffice.org and its descendants, Apache OpenOffice and LibreOffice, where it is called LibreOffice Basic. It is also known by older names: StarOffice Basic, StarBasic and OOoBasic. The language is domain specific, because its purpose is to script the OpenOffice application suite, so a typical program is a macro that walks through the paragraphs of a text document or works on the contents of a spreadsheet. Its syntax resembles other BASIC dialects such as Microsoft's Visual Basic for Applications, but the application programming interface it calls is quite different. From around 2005, with OpenOffice 2.x, partial support for the VBA interface was added under an Option VBASupport setting, and an Option Compatible directive turns on further VBA-like language features. LibreOffice has extended these compatibility options, and enables them automatically when it opens a Microsoft Office document that contains VBA code.
