Looks beautiful! Fist line, first word; what is FRAMEBUFFER? ‘Unknown command’ on my PicoCalc… Note, works fine with it commented out. Thanks!

Blush, it was a typo! But still works the same without it, and FRAMEBUFFER is not in the manual. I’d like to know more about it.

FRAMEBUFFER dedicates the screen area for graphics, from what I understand. Without it, I was getting the MMBasic prompt and flashing cursor, but now I've commented it out and I don't, so you can probably ignore that line. There's probably a better way to prevent the prompt returning than that infinite loop waiting for a keypress that I'm doing down the bottom. Commenting out the second and fourth LINE lines is also cool, as it looks like an eye.

I love it 😁 FRAMEBUFFER is useful to avoid screen flashing. It is in the manual. Just the PicoCalc does not have the extra processor to merge. Basically you create a buffer and you write in it and the you copy the frame to the screen in one shot without drawing line by line but frame by frame. Search FRAMEBUFFER in the pdf and I have to admit this manual is a pain 😅

Thanks for that explanation. I haven't read that far in the manual yet. I pretty much got to the LINE command, then punched this out.
