Taking a peek at the files inside the ZIPfile, we can gleam that most of the code was written in this century - but within the last few years even. They are re-using a number of very very old (particularly in the archive piece) functions which date back as far as 1993... I suppose there's no need to re-invent a perfectly good wheel? I think it's interesting for a number of reasons:
- The government actually published the source code - shows they have nothing to hide (no further comment made there...)
- Full Disclosure of source code can help make this system overall more secure
- This is interesting... Generated by MS Access 97?!

- Interesting... written in 1993 and re-used here
01/06/93: revision history starting date
07/09/93: Previous_Message handling changed, we now use the Prev_M index
as global variable
Fixed : the Prev_M was never incremented in Display_Messages
11/10/93: Display_Strings_URN was adapted so the names of the MASTER and BACKUP
disks are set dynamically in the messages, to allow multiple
17/11/93: The password is converted to uppercase either than lowercase,
due to a change in the Bell's programs.
There's a lot more of this stuff too... feel free to peruse and enjoy. If you're a real code-freak... try and figure out if there are any interesting ways to bypass/crash/hack this baby!
Here is the link to the Belgian Site hosting the code.
