This may not be a direction you are interested in, but it would be nice to have a basic outline of how to add additional tokens and functions to the interpreter. I add a WDT based reset command and token, but am having trouble adding commands with arguments (servo and motor speed commands). I stripped out the DWRITE code and dropped in a servo command which worked fine, but I don't understand the numbering attached to the tokens and how how they relate to the BASE token.

If you don't want to get into extensibility I fully understand.

This is great! I had reverse engineered most of it but my error was trying add a new commands as -128 and -129. The RESET I added does work as -128 but I will move it to the correct spot. Do we need to change the "#define NKEYWORDS 3+19+13+12+11+5+2+7+7+7+12" to include additional KEYWORDS?

Just tested that - it works on my 1284 SBC but have no idea why lol. I used the WDT library and this:
void soft_restart() { do { wdt_enable(WDTO_15MS); for (;;) { } } while (0); }

Just had a look. You added a keyword to position the cursor. This functionality is always there ;-) Try to do @x=10: @y=8: PRINT „Something“; The special variables @x, @y are the cursor postions. They are read / write. Best, Stefan

I suspected i might have missed something like that :D thanks. i wrote few commands to tinker with the terminal modes/resolutions just for the sake of tinkering
