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.

[slviajero]

Actually I wrote a little tutorial on how to extend the language:

https://github.com/slviajero/tinybasic/wiki/How-to-compile-Stefan's-BASIC-(and-how-it-works)#how-to-add-your-own-commands https://github.com/slviajero/tinybasic/wiki/How-to-compile-Stefan's-BASIC-(and-how-it-works)#how-to-add-your-own-commands

Maybe this helps. If you want to do something more complicated, please tell me.
I can create some template functions.

Best, Stefan

Ha, good to know there is this documentation :) I've been able to add few (not very useful) commands myself in my fork.

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.

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?

[slviajero]

not really anymore it was from an earlier code that was much simpler. by the way, reset exists alteady as CALL 0. xcall can be used as a general command for things like this.

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); }

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

[slviajero]

Its a little bit weird. The function void(* callzero)() = 0; compiles to a subroutine call to address 0. Flash address 0 on AVR is the start of the application code. Works on all Arduino Havard machine types of core.

Cool! As to the @X and related: you may have noticed the display buffer array @D() which is a character array of the display. Writing to it displays a character where ever you like. These concepts are not really „BASIC“ because the language design of BASIC is keyword oriented. I still like the way to work with variables. @C is an I/O stream variable (it is r/w for input and output) and @A is the number of characters available in the stream. @S is the I/O status i.e. if there is an end of file … condition.

Just a little example:

10 @.*** 20 IF C="#“ OR @S THEN END 30 @C=C 40 GOTO 10

Enjoy!

By the way, just looked at your code. Impressed! I saw you implemented an INKEY. This was already there. It is called @C :-). Best Regards, Stefan
