clock_set_multicast_type

	clock_set_multicast_type(mcast_type.i4.v)

   	This function affects the operation of the accelerator clock functions
   	(lckclk_c and friends).  It determines which clock multicast 
   	events 0-255 refer to.  The Acnet console computers listen to 4
   	clock multicasts for the TCLK, TEST, PROJ, and NML clocks.  

   	Programs running in a console instance environment will use the
   	default clock multicast type last selected in the utility window.
   	Other programs use TCLK by default.

   	The clock_set_multicast_type function will override the above default
   	for the current program.

	mcast_type	multicast clock type
