Int E0 Fn 0001  - Pcrobots V1.41 - "movement" - Start Moving               [g]

   AX = 0001h
   BX = speed (0-maximum for robot)
   CX = direction (0-359 degrees)

Return: nothing

Notes: the speed will change to the specified value at the maximum
     acceleration the robot is capable of; if the robot is already moving
     faster than its maximum maneuverability speed, it will not be able
     to change direction
   this call also terminates the current robot's turn
