bpm_is_tbt_trigger_enabled

	status.i4.v = bpm_is_tbt_trigger_enabled([house.i1a.r]
						 [,enable_info.g.v])

	This routine determines if BPM turn by turn triggering is enabled
	for the machine last requested by a call to bpm_machine_c.

	[house]		name of house to control (If a value of NULL is
			passed for this argument, all turn by turn timers
			for the current machine will be affected.)
			(default is NULL)
	[enable_info]	additional information for enabling/disabling
			(BPM_MAIN_INJECTOR -> structure of type
					      BPM_MI_TBT_TRIGGER_INFO,
			 BPM_RECYCLER -> structure of type
					 BPM_RECYCLER_TBT_TRIGGER_INFO)
			(default is NULL)

	This function returns ACNET status values as follows:

	TRUE			turn by turn triggering is enabled
	FALSE			turn by turn triggering is disabled
	CBS_INVARG		invalid house string passed
	CBS_NOTYET		not supported for the currently selected
				machine
	otherwise		other ACNET error

	This function requires the following include files:

	cnsparam_h, ul_cbsaux/bpmuti.h, acnet_errors_h
