Database source code?


Ray Gillman

Recommended Posts

Have you noted or cataloged any database source code in 8-bit basic or machine language? I like the anticdb.exe but no source code means no enhancements are possible. Basic would be ideal because lots of hours of messing with Ostrowski's Turbo Basic would allow me to get results more quickly. What I was thinking was more of a 16MB floppy DB that could store loads of data on a single floppy (image) and when run at turbo speed emulated might make an effective place to store some information.  Handy store an ATR click it to launch the Altirra to quickly access your data and info.  Could be great for contacts, recipes, passwords, manifests, catalogs etc etc

Another from scratch approach would be to take the source for a simple hash (aka associative array or map) and port to another language.

 

I once took, and the source is long lost but it wasn't hard, a short C simple example (off google) of an associative array and ported it to CC65 quite easily.

Here's an article from Compute! Magazine with Atari BASIC source code to a database.  It's by Ron Marcuse, who together with Lynn Marcuse authored several productivity apps for APX, including "Data Management System" which is very likely a more advanced version of the code in this article.

They also wrote this machine language sort utility, which is likely geared well to work with their database:

And that same issue has an article with BASIC source code (though not Atari BASIC, looks like it's for the Apple II) for a hash function to use with database storage:
