Parameter information

Variable Name	Size	Description
x	double	The input variable for the defined HAVSIN.
x0	double	The starting point for the HAVSIN function.
h0	double	The initial value for the input variable (within the range of x≤x₀).
x1	double	The ending point for the HAVSIN function.
h1	double	The initial value for the input variable (within the range of x≥x₁).
order	int	1) order = 0 2) order = 1 3) order = 2
value	double	1) order = 0 2) order = 1 3) order = 2
error	logical / int	If an error is encountered in invoking Predefined subroutine, this variable becomes true. This variable must be declared as a logical variable.
