+**  IIW_RIGHT -- Write down to the QL parser a string
+**	for a target list of anything but a tupret.
+**
+**	Parameters:
+**		string -- a string which contains the target list
+**			of a QL statement, where values from C variables
+**			to be plugged in are flagged by the construct
+**			'%<dbs_type>" a la printf(). String is left
+**			unchanged.
+**			To escape the '%' mechanism use '%%'.
+**
+**		argv -- a vector of pointers to
+**			variables from which the values flagged by the '%'
+**			mechanism are taken.
+**
+**	Usage:
+**		argv[0] = &double_raise;
+**		IIw_right("dom1 = i.ifield * (1+%f8)", argv);
