Code?

After having posted a number of listings of my code, I have decided not to provide complete listings of my modules.

I reckon if you are interested in learning to code, you really should be using my posts to generate your own code and modules. Not just copying mine.

If you are only interested in copying my code to generate images, that is not why I wrote these posts.

So, sorry, but I am, as of 2022.07.22, going to remove the code listings from all the code listing posts.
