Much more notable, however, was Basic XL's FAST command. Atari BASIC was notoriously slow, due larger to two problems. One was that the floating point routines in the Atari OS ROMs were very slow, and every number in BASIC, even line numbers and array indexes, were sent through this code. The other issue stemmed from the way Atari BASIC handled GOTO and FOR/NEXT commands. FAST fixed the later of these two; when this command was encountered within a program, Basic XL cached the location being pointed to by the GOTO and FOR/NEXT loops. This made the jumps dramatically faster than Atari BASIC, which had to scan through the entire source code every time through a loop.

Basic XL was widely lauded in the press, and some stated it should be renamed Atari BASIC and built-into every machine. However, the release of [TURBO-BASIC XL] a year later largely ended the market for Basic XL.
