Instructions:
1: Place the toy on a 5 x 5 grid
using the following command:
PLACE X,Y,F (Where X and Y are integers and F
must be either NORTH, SOUTH, EAST or WEST)
2: When the toy is placed, have at go at using
the following commands.
REPORT – Shows the current status of the toy.
LEFT – turns the toy 90 degrees left.
RIGHT – turns the toy 90 degrees right.
MOVE – Moves the toy 1 unit in the facing direction.
EXIT – Closes the toy Simulator.";
