This program is a simple Conway's Game of Life for Casio Graphic calculators.
Create matrix A and B, both 9x23. In matrix B enter the starting pattern; 1 is alive, 0 is dead.
Once you start the program it'll start processing from cycle to cycle. It takes ~30 seconds per cycle.
To stop it without messing up the pattern stop it while the current pattern is being draw, not while it's being processed.
The -> represents the arrow under the red 'L' on your
calculator, the one that assigns values to variables.
The » represents the operator which executes the
instruction to its right only if the instruction to
its left equates to 1. (PRGM>JUMP>=>)
The whole program takes up 718 bytes, and could be cut down by cutting out the text and optimizing the code. The NOT= (used only once) represents the 'not equal' sign (the equal sign with a cross through it). (PRGM>REL>)
