This article is about Turbo-Basic XL, a BASIC dialect for the Atari 8-bit family. There is a different article on the unrelated  Borland Turbo BASIC.

Turbo-Basic XL is an advanced version of BASIC for the Atari 8-bit family of home computers. It is a compatible superset of the more common ATARI BASIC. A Turbo-Basic XL compiler was also made available that created binary executables (for further speeding up program performance).

Among the extra features of Turbo-Basic XL, added to ATARI BASIC, are the following:

• enhanced sound and graphics commands
• more flexible I/O commands, including disk access
• structured programming constructs
• simple debugging facilities

Turbo-Basic XL was developed by Frank Ostrowski and published in the December 1985 issue of German computer magazine Happy Computer .
