This educational software was written for the Thomson line of 8-bit computers in Microsoft BASIC. It will test pupils for their ability to perform additions in columns, with or without a carry. Incorrect additions will raise the sea level below the hero, standing on a cliff. If too many incorrect answers are given, the hero will drown before it can be saved by an incoming rescue helicopter.
This program was written on a TO9 computer by then primary school teacher Daniel Nocera, as part of a country-wide training program into IT literacy, following on from the “Plan Informatique pour Tous” launched in 1985.
The program is distributed under the GNU GPL version 2 or later, at the user's convenience.
The software was authored by Daniel Nocera (original programming) and Bastien Nocera (digitisation and further development).
