The program was [most likely] originally written in 'C', or any other
language that makes use of the curses library for screen manipulation.
Once written and compliled, the output was redirected into a file, while
the user had TERM=vt100 set. [That is why it only works on a vt100.]

The industrious user may want to examine the file by dumping it, or even
using an emacs which displays control codes as ^A rather than it's
affect. Here, you will find a huge series of control codes which instruct
the cursor to go in 'non-standard' directions, i.e. up, down, & backwards.

Happy Hunting!
