language that became available for any new CPU. FORTH is unusually
compact and powerful in small CPUs.
My first contact with Forth was by way of Postscript. It is in
every way Forth with graphic primitives added. Still have to
books for it as all of the basic Forth operators are there.

Color FORTH. While it is written for the Intel x86 CPUs (PCs of
course), there are a lot of fascinating ideas embedded in it. Things
like single keystroke keywords, using color to illustrate whether a
word is program or data, whether it should be executed immediately or
compiled, etc. Color FORTH does unbelievably fast compilation, and can
be reverse-compiled to recreate source -- in fact, the system is
stored in source form, and gets compiled each time you boot it up. The
entire source fits on a single 1.44 meg floppy disk!
