The double buffering is the use of more than one buffer to hold a screen data. So that a "reader" will see a complete (though perhaps old) version of the data, rather than a partially updated version of the data being created. It is very commonly used for computer display images. ==== EXAMPLE ==== DOUBLE BUFFER ==== ABBREVIATION ==== Db Bf ==== AVAILABLE ON ==== * Commodore 128 (MOS 8502) * Commodore 64 * * Olivetti Prodest PC128 ==== ANY PROBLEM? ==== If you have encountered a problem using this command, if you think there is a bug or the explanation is unclear, please [[https://github.com/spotlessmind1975/ugbasic/issues/new?title=ISSUE ON DOUBLE BUFFER|open an issue]] for this keyword on GitHub.
