Atari BASIC A++ 1983?

[atari65xenajm]

Hello all,

 

I recovered a few 5.25" diskettes of mine that I owned since 1990. One of those diskettes had a loading menu with two programming languages: 1) Atari LOGO, which is known and can be found many places online. The other that is puzzling me is the other one: 2) Atari BASIC A++. It says it is version 4. Another diskette has a few BASIC programs written in this dialect of BASIC, with a .AXX extension.

 

Attached is a snapshot of what it looks like, and also the disk .atr image that I am referring to.

 

Can someone tell me if this is truly BASIC A++, or is that that this is a hacked text of some other BASIC? (Note: I tested Basic XE, OSS, and Basic++, but I am sure it is neither of those, because as I loaded the .AXX file, the file did not run. It only ran on this Basic A++ language!).

 

I did not find any where online any reference or mention to an Atari BASIC A++, hence my post.

 

Thanks!

It appears to be a version of OSS BASIC A+, as the statement table is similar if not identical to OSS BASIC A+ 3.04. The core program format is the same as Atari BASIC but statement token values differ, which is why the programs aren't compatible with the other BASICs.

Thank you! I tested the program on OSS BASIC A+ 3.04 and it ran and worked just fine.
