status.i4.v = acnet_node_name_exists_in_db(node_name.i1a.r [,node.i4.r]

	This routine determines if an ACNET node name exists in the database.
	A value of NULL can be passed for returned arguments which are not

	node_name	node name to check
			(up to NODE_NAME_LEN characters)
	[node]		returned ACNET node (constants are in 'nodedefs')
	[db_status]	returned ACNET status of node database access

	This function returns ACNET status values as follows:

	TRUE			node name exists in the database
	FALSE			node name does not exist in the database

	This function requires the following include files:

	cnsparam_h, cbslib_h, nodedefs_h, acnet_errors_h

	node_info_db, front_end_type_c, is_front_end_node_c, node_is_up_c,

	C/C++ usage:

	static const char	node_name[NODE_NAME_LEN_LEN+1] = "MI1";
	int	status;
	int	node;
	int	db_status;

	status = acnet_node_name_exists_in_db(node_name,&node,&db_status);
