**BASIC A+** is an implementation of the [BASIC](/source/BASIC) programming language for [Atari 8-bit computers](/source/Atari_8-bit_computers) introduced by [Optimized Systems Software](/source/Optimized_Systems_Software) in 1981. It was developed by the team that created [Atari BASIC](/source/Atari_BASIC), which shipped with each computer, and is compatible. BASIC A+.[1] BASIC A+ adds new features to the language, such as IF..ELSE..ENDIF statements, support for hardware features like [player/missile graphics](/source/Sprite_(computer_graphics)), and commands for [debugging](/source/Debugging). While Atari BASIC is an 8 [KB](/source/Kilobyte) ROM cartridge, BASIC A+ is [floppy disk](/source/Floppy_disk) based and uses 15 KB of the computer's RAM, leaving 23 KB available for user programs in a 48 KB Atari 800. BASIC A+ shipped with a supplement to the Atari BASIC reference manual as its documentation.

Optimized Systems Software followed BASIC A+ with the cartridge-based BASIC XL, then BASIC XE.
