!Background
[Atari BASIC] was originally written by a 3rd party company, Shepardson Microsystems. An early version was delivered in late 1978 for demonstration purposes so Atari could show it at the CES in January 1979. To the programmer's surprise, they learned that Atari started burning this version to ROM cartridges as the final product. This was in spite of a number of bugs having been found and corrected in the meantime.
Shortly after the release of Atari BASIC, the owner of Shepardson decided to dissolve the company. The Atari staff formed their own company, Optimized Systems Software (OSS), and purchased the licenses to the Atari products. Basic A+ was one of OSS's first products, consisting largely of the bug-fixed versions of Atari BASIC along with a few expansions. Among the notable additions were PRINT USING (for formatted output), trace and debug enhancements, and direct DOS commands.
Too large to fit on a 8k ROM, the product was sold on disk only. Because BASIC A+ had to be purchased, programs developed using its extended features could not be shared with people who did not own the interpreter. A+ was never particularly popular, and soon superseded by the greatly improved [Basic XL].

!!Descriptions
From Wikipedia:\\
Atari BASIC had been designed to fit in a single 8k cartridge, with an optional second cartridge adding additional capability (the Atari 800 home computer featured two cartridge slots). However, the second cartridge was never produced. Instead, OSS produced a disk-based product called BASIC A Plus (or BASIC A+), which was compatible with Atari BASIC but corrected several bugs and added quite a few features. Among the notable features were PRINT USING (for formatted output), trace and debug enhancements, direct DOS commands, and explicit support for the Atari computers' exceptional graphics hardware. Because BASIC A+ had to be purchased, programs developed using its extended features could not be shared with people who did not own the interpreter. BASIC A+ was available on disk only.\\
