Contents of README:focal (FOCAL language interpreter) FOCAL is an interactive interpreted programming language based on JOSS and mostly used on DEC PDP series machines. It is an ancestor of (or at least an influence on) the BASIC language. For more information on FOCAL, see: https://en.wikipedia.org/wiki/FOCAL_(programming_language) This implementation is by Dave Conroy and Akira KIDA. It comes from Eric Raymond and John Cowan's Retrocomputing Museum: http://www.catb.org/retro/ See /usr/doc/focal-$VERSION/focal_doc.txt for the language specification. See /usr/share/focal for sample code. Loading and running a FOCAL program is done like so: $ focal *lib call program.foc *g Enter "quit" at the * prompt to exit. There is a small archive of FOCAL programs available here: ftp://ftp.pdp8.net/software/games/focal/ ...although not all of them are compatible with this version of FOCAL. |
