Basic XE#

OSS, 1984

Basic XE is the ultimate development of the original Atari BASIC code, after it was taken over by Optimized Systems Software (OSS). It was a further expansion of Basic XL that made use of the XE machine's extended memory. Like Basic XL, it included a number a features that improved Atari BASIC's notoriously slow performance, added new commands for player/missile graphics and other features, all while remaining backwardly compatible with the original Atari BASIC and running it's programs much faster.

The changes between Basic XE and Basic XL are minor, mostly related to handling the increased RAM capabilities of the XE series. However, 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 also have a Basic XE cartridge. However, programs that used only the Basic XL extensions could be written in 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.

To enable building BASIC XE 4.2 for M091 cartridges, a change has to be made in the D1:MASTER2 file: in line 290, change the value of _27128 to 1. Then follow the normal assembly steps. It results in an object file that loads the four banks to the $3000-$6FFF area in the "1M09" order. Retrieving the bank data in a correct order results in an M091 ROM image.

Thank you so much Tomasz 'Kr0tki' Krasuski for the info in building the runtime, we owe you so much. :-)))
