double	w [12]

double	g [13]

double	psi [12]

double	x
	Independent variable.

double	h
	Appropriate step size for next step. More...

double	hold
	Step size used for last successful step.

double	told

double	delsgn

unsigned	ns

unsigned	k
	Appropriate order for next step (determined by code). More...

unsigned	kold
	Order used for last successful step.

bool	isnold
	"iflag_sign_old": whether the user-provided iflag was positive (controls whether solver is allowed to overshoot and interpolate)

bool	nornd
	Indicates whether extra precautions are necessary to reduce round-off error (probably an abbreviation for "no_round_off_error")

bool	phase1

bool	start
	`true` on first step, `false` otherwise
