Take a close look at the following thread: Unofficial PicoCalc PicoMite/WebMite firmware release thread (V6.00.02). It will give you a lot of information on using MMBasic on the PicoCalc. Note that the version of MMBasic that comes with the PicoCalc is old, and its use is not recommended; you should use the latest version of MMBasic 6.00.02 modified to run on the PicoCalc as mentioned in that thread. Also, you may want to update the firmware on your PicoCalc’s STM32 to help resolve some keyboard issues.
