I’m using the Pico2w in my PicoCalc.

Hmm where are you launching the program from?

Just now I tested these on both Pico2W and the Pico that comes with the Calc:

- `Library -> Applications -> MMBasic` (no issues)
- `Library -> Utilities -> File Browser -> picoware -> mmbasic` (no issues)

And the other day when I posted the script ([here](https://forum.clockworkpi.com/t/picoware-open-source-custom-firmware/18536/945)), I tested with ThonnyIDE on the Pico2W.

The `clock.bas` program uses `CLS`
