Commander X16 BASIC Tutorial: Lissajous Curves

"Lissajous Curves"
A codereview of this small BASIC Program for the Commander X16.
The programm is easy portable to any other Basic dialect of any 8-/16-bit homecomputer.
Code:

Amazing work 🎉

[@GeorgesChannel]

Thanks. I did a version with dynamic col and row count.

[@pburdick7]

Well done!

[@GeorgesChannel]

Thank you for watching!

The result is Beautiful! It's pronounced Lissazhou.

[@GeorgesChannel]

Thanks for the correction. I should have looked it up or ask you.

​@@GeorgesChannellike this linear code review. It's kind of fascinating. And the result is Beautiful! Or you can use the same J as in Jungle 😊
