This is a temporary lesson: whilst Arcs get fixed.

Not sure if this is still useful.

Lesson A12.

Tiling Lesson.

Arcs Lesson. There are three types of values above. Numbers, text and Colours. Try changing the numbers, save the file and you should things move around the screen. Congratulations! you are now a programmer. But, but, you respond, there's loads of magic going on here that I don't understand. All programmers rely on magic, and of course the first thing we should know about magic is it doesn't always work. I will try and explain how some of the magic works, but in programming there's always more magic to decode.

The second type is text. Programmers refer to text as Strings, for some reason. I shall use the term string from now on. Strings start with a " quotation mark and end with a quotation mark. Change the text in on one of the strings, save the file, and you should see the text change on the screen. If you try replacing a string with a number or replacing a number with a String, the compiler will complain, and you will get an error message. The third type is Colour. Note Colours must have the correct capital letters. You can just try guessing the colours, or you can google / duckduck web colours to see what is available. Again put a Colour where a number or a string is expected or vice versa and the compiler will complain.
