DOUBLE BUFFER

SYNTAX

   DOUBLE BUFFER

PURPOSE

The DOUBLE BUFFER instruction activates, where available, the double buffering functionality. 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)
