If you like Forth, you could also have a look at PostScript. It is more that
a
simple Page description language, it is a true programming language . It is
stack-based, with some file access, user input and so on. You define your
own functions and reuse them later. like this:
%!
/mt {moveto} def
/lt {lineto} def
/rl {rlineto} def
/rm {rmoveto} def
/mm { 2.835 mul } def
/s {show} def

...and so on. So if your printer has enough mem and a good cpu (and the
output is to be printed), it can do the computing in place of your computer!

I personnaly find that also fun ... and sexy 
 - if you'd like to try but haven't such a printer you can get Ghostscript
(a free PostScript shell, for many platforms)  at  www.cs.wisc.edu/~ghost/

If i remember right Fouth does just that....I loved it...you made your
own commands from your own commands that were based on a very simple set
of commands...if i remember right you could also change that set of
commands....Ill send you MVP Fourth if you want...i only used it to play
around with cuz i found E just a month or so after i found it..
