You forgot to include the gforth list.  I also highly recommend you get onto comp.lang.forth.  Try it on if you aren't used to usenet.


Yes, there are many ways to run Forth without Windows, or without any OS for that matter.  However, it takes a deep understanding about how CPUs and MLB's operate.  You sound like you have a lot to learn before you are ready to tackle that.  On the other hand, SVFIG ( is having an Arduino Day ( tomorrow.  You might want to watch for the postings that will follow, or if you are in the area, just show up.

One of you fellas said something about "running on bare metal".  How is that possible without Windows?  Is it possible to put gforth onto an EPROM or the like and run it from a custom built system?  That.... would be COOL.  =)

Yea, the big blue paper version is the one I've got.  :). I'll be making a new gforth video tonight discussing stack manipulation... DUP, ROT, DROP, etc...

Also want to learn to redefine characters and place them on the screen---- still don't know how to so that in gforth.  Any pointers?  Maybe someone could direct me to a chapter in the manual.  Is character redefinition based on hex code?  For example:

Char(129) "56AD12FFF201BCD4"

That's assuming we're talking about 8x8 pixel chardefs.  Thanks for you help!!!
