/*******************************************************************************
 *	TmsControlClient2.cpp	TMS API example code
 *			T.Barnaby,	BEAM Ltd,	2007-02-07
 *******************************************************************************
 *
 *	This is a very basic example of using the TmsApi to set the
 *	TMS's cycleNumber and cycleType.
 *	It is designed to give an overview of using the API.
