Where next

You can run Koskari, read its results and its errors, and write a program from calls, names, choices, functions, lists, and text.

What should I read next?

The Guide, starting with Model of evaluation. It names what happened in every chapter here: reading text into forms, and evaluating forms into values.

Do I need the reference?

Not yet. Keep the glossary open for a word you do not know, and go to a form’s reference page when you want its exact rules.

I know Python. Is there a shorter way?

From Python sets each Python spelling beside its Koskari one. It ends with worked examples to copy and change.

How do I get better?

The same loop as every chapter: decide what a program will do, run it, and read what it did. Change one line at a time.
