!Background
Atari BASIC is the "standard" BASIC dialect for the 8-bit series. It was originally sold separately as a (relatively expensive) 8k ROM cartridge. Starting with the 600XL/800XL, the ROMs were included inside the machine. There are three versions, the original version, retroactively known as Revision A, and the updated Revision B and C which fixed various bugs.

!! Books
Atari originally licensed the 6502-assembler code for Microsoft BASIC. This came in two versions, one that was about 7900 bytes that used a 32-bit (6-digit) floating-point number format, and another that was closer to 9000 that included an expanded floating-point format with a 40-bit (9-digit) numbers. The vast majority of 8-bit machines used the larger 9k/40-bit version, and then further expanded it with additional functions for basic input/output. For instance, the BASIC, character set and I/O in the early PET machines was supplied in a total of 16k of ROM.

The Atari machines were originally designed as games consoles that would replace the Atari VCS, and like those machines, software would be supplied on ROM cartridges. ROM was still relatively expensive at the time, so they expanded it from the 4k of the VCS to the luxurious size of 8k. When the project moved to a computer, a BASIC interpreter was required and Atari naturally licensed MS's code. Atari programmers started with the smaller 7900 bytes version and struggled to cut fit it in the pre-selected 8k cartridge format. That was hard enough of its own, but they really wanted to add additional instructions to take advantage of the Atari's graphics and sound. Eventually, sometime in the summer of 1978, they gave up and went looking for a 3rd party to do it for them.

Atari approached Shepardson Microsystems Inc, or SMI for short, who had written a number of 6502-based products and a series of BASICs for other machines. They proposed a simplified syntax and the cutting of a number of rarely-used features, leaving more room for new commands for graphics and sound. Even then, the result required about 10k, so to cross the remaining gap to 8k, some of the core libraries were moved out of the language and into the operating system ROMs. This had the side-effect of allowing any other language on the Atari to use these routines as well.

By the time SMI was hired, Atari was in something of a rush to get a working BASIC. They were planning to show the machines in January 1979, using the working MS version, but then sell the machines later that year with the SMI version instead. The original contract required SMI to make its final delivery in April 1979, but it contained bonus clauses if they finished early. They did: a working version was delivered in October 1978, so Atari to that to CES instead. To SMI's surprise, they learned that Atari had begun burning that version to ROM for sale, even though it had several known bugs. SMI offered an updated version with various fixes, but Atari didn't bother using it, and instead shipped the buggy version for several years.

In order to fit the code into a 8k ROM, two major pieces of code were moved out of the BASIC into the OS ROM. The first was a set of graphics routines to set up the screen, draw lines, and similar tasks. The second was the floating-point math system, based on a new implementation of the 6-byte binary-coded-decimal (BCD) format SMI had designed for the Z80-based Cromemco machines. Both libraries were notoriously slow. Generally, Atari BASIC was among the slowest BASICs of its era, both due to the OS code and two problems involving loops.
The performance issues led to a profusion of 3rd party BASICs, some of which continue to be developed to this day. By replacing the math libraries and fixing these two loop issues, speed improves on the order of 3 to 5 times in most programs, and this is a common feature of 3rd party BASICs like [Turbo-BASIC XL] and [Altirra Basic]. For even higher performance, [FastBasic] uses a p-code system that can be quickly interpreted.

!Design notes
Atari BASIC has some key differences with the more common MS-derived BASICs found on most contemporary machines. Generally, one can describe Atari BASIC's design philosophy as "modeless" and "orthogonal".
Most BASICs of the era had the concept of "immediate mode" and "program mode", and some commands could only be used in one mode or the other. A good example in MS BASIC is the {{LIST}} command, which could only be used in immediate mode, at the "command line". Atari BASIC removed this limitation, one could write a program consisting of {{10 LIST}}.
Additionally, most BASICs had commands that read input or produced output, for example, the {{INPUT}} can be thought of as the opposite of {{PRINT}}. Atari BASIC was orthogonal in that every such command had a partner. For instance, {{LIST}} produces output, so the new command {{ENTER}} reversed this, reading a program listing from a device. This opened up a number of possible overlay techniques that other BASICs lacked.
The most noticeable difference between Atari BASIC and MS-derived versions is the string handling. Atari BASIC used a greatly simplified system of character-arrays instead of the dynamic strings in MS. This meant that all strings had to be predefined using {{DIM}}, and their length could not be changed during run-time. There are a number of advantages to this approach, notably speed and lower memory usage, but this means conversion of standard programs from MS listings may be difficult.
!What's missing
In addition to differences like string handling, Atari BASIC also lacked some of the less-used features found in MS BASIC. Among these are...
* {{TAB}} and {{SPC}}, for formatting output
* {{PRINT USING}}, which formatted output (rarely supported on small machines)
* {{INPUT "prompt", A$}}, which printed the prompt and placed the cursor at the end
* {{INKEY$}}, which read the keyboard without pausing (unlike {{INPUT}})
* {{DEF FN}}, which defines mathematical functions
Most 3rd party BASICs for the Atari added many of these features, and more.
!What's new
To allow BASIC programmers access to the advanced features of the system, Atari BASIC added commands for defining the GRAPHICS, changing COLORs, MOVEing and drawing a DRAWTO, playing SOUND, and others.
