Applesoft BASIC was the second dialect of BASIC supplied on the Apple II computer, superseding Integer BASIC. Applesoft BASIC was supplied by Microsoft; Apple was looking for a new version of BASIC for the Apple II Plus computer with 48 KB of RAM, and after their success with Altair BASIC, Microsoft was the BASIC vendor of choice. Apple licensed a 10 KB assembly language version of BASIC called "Applesoft". It was similar to (and indeed shared a common code base with) BASIC implementations on other 6502-based computers, such as Commodore BASIC: it used line numbers, spaces were not necessary in lines, plus, while being much slower, it had some killer features that Integer BASIC lacked: BASIC (Beginners All-purpose Symbolic Instruction Code) is a family of high-level programming languages. ...

- Atomic strings. A string is no longer an array of characters (like in C); it is instead a garbage-collected object (like in Scheme and Java). This allows for string arrays;
DIM A$(10) resulted in a vector of ten string variables. - Multidimensional arrays.
- Single-precision floating point variables with an 8-bit exponent and a 31-bit significand. Along with this came a trigonometry library.
- High-resolution graphics.
CHR$, ASC, STR$, and VAL functions for converting between string and numeric typesLET statement optional- User defined functions (just simple one-line functions with simple parameters, but written in BASIC as well).
However, relatively few action games were written in Applesoft BASIC, for several reasons: The C Programming Language, Brian Kernighan and Dennis Ritchie, the original edition that served for many years as an informal specification of the language The C programming language is a standardized imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. ...

- In this era of carefully counting clock cycles and limited memory, it was silly to write speed-dependent programs that ran only through a runtime interpreter.
- The use of real numbers for all maths operations created unnecessary overhead and degraded performance of programs written in Applesoft BASIC. Integer variables had to be converted to reals before math could be performed on them; they were then converted back to integers. Microsoft did not optimize this.
- So-called shape tables are a slow alternative to bitmaps. No provision existed for mixing text and graphics, except for the limited "Hardware split screen" of the Apple II (four lines of text at the bottom of the screen). No provision was added in the 128 KB Apple IIe and Apple IIc models' BASIC interpreters for the new machines' extra memory and double-resolution graphics, or for the Apple IIGS's 16-color mode. (Beagle Bros offered machine-language workarounds for these problems.)
- The program was stored as a linked list of lines; a
GOTO took O(n) (linear) time. - No sound support.
- The closed source movement was just beginning; software publishers found it was harder to crack a compiled binary than an interpreted source.
