WHAT IS IT?

This model is a test of student's coding skills.

HOW IT WORKS

The model will generate several errors when you try to click Setup of Go. You must "debug" the code before it will run.

HOW TO USE IT

Try clicking "setup". Use the ERROR message(s) produced as a clue to fixing the code.

THINGS TO NOTICE

There are several errors in this code. Fixing one "bug" may reveal another you were unaware of. Try to avoid creating new bugs in the process of fixing the old ones!

THINGS TO TRY

Use the "Programming Guide" and"NetLogo Dictionary" to help you figure out what is wrong with the code as written. Sometimes things are just mispelled or written with the wrong "syntax" (for example, a hyphen, a space or a set of brackets may be missing).

EXTENDING THE MODEL

Feel free to add new procedures to this model once you have it working, or move on to making your own model.
