Very nice, thank you for sharing this! To try it with GnuCOBOL, compile it with: $ cobc -F -x game-of-life.cob The "-F" switch instructs GnuCOBOL to use

Very nice, thank you for sharing this! To try it with GnuCOBOL, compile it with: $ cobc -F -x game-of-life.cob The "-F" switch instructs GnuCOBOL to use so-called free format of the source code, and "-x" builds an executable program, "game-of-life", which you can run with: $ ./game-of-life Use Ctrl-c to interrupt it. A major attraction of COBOL is the ability to quickly construct user interfaces for efficient entry and processing of records.
