Programming an RCX with Logo Commands

I use MicroWorlds EX Robotics to teach 7th graders to program Lego RCX robots. It took me a lot of trial and error to find simple ways to control the input and output for these units; to find efficient programs that direct switches and reflectors to make the RCX do useful things. The accompanying help guide for MW EX provides overly complex examples for just learning the basics, so I figured it might be helpful to post the examples I'm using to get my students started on creating interactive robots.
