Small Basic Challenges of the Month – September 2016

Welcome to the September challenges, hosted by LitDev!

Please jump in with your solutions in this forum thread:

These challenges are intended for people who are learning to program for the first time or for those returning to programming who want to start using Small Basic.  Some will be easy, some will be hard – but they will all make you think, and more importantly be GREAT FUN!

Please post your solutions / partial solutions / questions / feedback etc. into this thread that will remain ‘sticky’ for the month.  The only rule is that your solution must use standard Small Basic methods (no extensions).

It would be good if people could post their problems with these challenges so that a discussion can start so that everyone can learn from each other.

We may extend these challenges over into a second month if solutions and questions are still coming in.

Turtle Challenge

Multitasking Challenge
