# SIDE LINER #
# #
# This is a general purpose robot that demonstrates may basic techniques. #
# It also demonstractes an advanced technique using the Blocking() command. #
# This robot moves up and down the right wall. Its main goal it to never #
# stop moving. #

# The following use of the Blocking() function is relatively advanced.
# If blocking were left on, this section would remain active until
# Continue() ended. Since autoscanning is a lower priority event, we
# would be moving blind! Turning blocking off prevents this section
# from blocking on Continue(). This ends this section allowing autoscan
# to be called normally. The orignial call to Ahead() or Back() in
# 'Core' will be blocked since blocking was on when they were called.
# There are other alternatives, but each has at least one major problem.
# Play around with other alternatives and you will see what I mean.
