Variable Name	Size	Description
x	double	Specify the independent variable.
x0	double	The x value at which the STEP function begins.
h0	double	Initial value of the STEP function.
x1	double	The x value at which the STEP function ends
h1	double	Final value at which the STEP function
order	int	1) order = 0 2) order = 1 3) order = 2
value	double	1) order = 0 2) order = 1 3) order = 2
errflg	logical	If an error is encountered in invoking Predefined subroutine, this variable becomes true. This variable must be declared as a logical variable.
