ATARI ARCHIVES - REVERSE

[Pjot]

For fun, I have ported an old BASIC game from 1978 to BaCon. I have tried to leave the original code as original as possible. There were three changes:

(1) BaCon has no GOSUB, instead I have used SUB.
(2) BaCon does not use line numbers, so for every GOTO I have created a LABEL with a linenumber.
(3) BaCon has a different RANDOM implementation so this was changed slightly.

The URL of the original game is: www.atariarchives.org/basicgames/showpage.php?page=135

Regards
Peter
