OSS released [Basic XL] in 1984, adding many new features as well as the FAST command. FAST cached line numbers that were the target of jumps (GOTO and FOR/NEXT loops), addressing one of the two major reasons for the notoriously slow performance of Atari BASIC. The main addition to Basic XE was a solution to the other big problem in Atari BASIC, the low-performance math code.

With that exception, the changes between Basic XE and Basic XL are minor, mostly related to handling the increased RAM capabilities of the XE series. However, Basic XE it did not include the AUTORUN runtime library found in Basic XL, meaning that programs that used Basic XE's functionality could not run on machines that did not have a Basic XE cartridge. However, programs that used only the Basic XL extensions could be written in Basic XE and then linked to the XL's AUTORUN runtime library.

The release of [TURBO-BASIC XL] at roughly the same time as Basic XE meant that Basic XE was largely forgotten in the market. TURBO-BASIC had all the features of Basic XE and many more, and also shipped with a compiler that not only made stand-alone programs but ran them dozens of times faster as well.
