# This file was automatically created for V-REP release V3.4.0 rev. 1 on April 5th 2017
# This example illustrates how to execute complex commands from
# a remote API client. You can also use a similar construct for
# commands that are not directly supported by the remote API.
#
# Load the demo scene 'remoteApiCommandServerExample.ttt' in V-REP, then
# start the simulation and run this program.
#
# IMPORTANT: for each successful call to simxStart, there
# should be a corresponding call to simxFinish at the end!
