/*
**  IIw_right -- Write down to the Quel parser a string
**	for a target list of anything but a tupret.
**
**	Parameters:
**		string -- a string which contains the target list
**			of a quel statement, where values from C variables
**			to be plugged in are flagged by the construct
**			'%<ingres_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);
**
**	Required By:
**		all the parametrized statements except "tupret_p".
**
**	Error numbers:
**		1004 -- bad type in parametrized statement.
