This document provides the program write-up for a FOCAL version of the game LIFE, originally attributed to John Horton Conway. The document explains the basic rules of the game—involving cells, isolation, over-population, and new cell generation—and details how to operate the software on a PDP-8 computer with either 4K or 8K memory. It includes instructions for setting the matrix size, entering the X and Y coordinates for occupied cells, and generating successive iterations of the matrix. The text also includes references to related literature from 1971 and provides the complete source code listing for the program.
