Very likely a DOUBLE PRECISION COMPLEX datum is represented by what in C
would be expressed as a structure:
	typedef struct
		{
		double	re;
		double	im;
		}	dcomplex;
Because of call-by-reference, when one of these data is passed as a
subprogram argument the C equivalent would be to pass a pointer to the
datum.
