Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Doesn't work like that. The vartbl entry still contains a pointer so nothing else needs changing. For short strings it points to the second element of the dimension array which is repurposed to contain the string


Ah right, thanks Peter, that would work too. Isn't the dimension array (minus one element) on the RP2040 large enough to hold 10 bytes then ? ... but the code is copied from the CMM2 which had a lower value of MAXDIM, that explains it.
