’MAIN ROUTINE
MOVE P, P0 ··················· Moves to the initial position.
*ST:
SEND VCMD$ TO CMU ············ Sends the command.
SEND CMU TO P10 ·············· Receives the destination point to move
to.
MOVE P, P10 ·················· Moves to the reception position.
GOTO *ST
• "SEND xxx TO CMU" outputs the contents specified by "xxx" through the RS-232C.
