Evaluate a spline function

Hi, I have used the SplineFit to interpolate my data points for a curve y(x) and now would like to get the interpolated value between my data points. Is there a easy way to evaluate y(x) by directly inputting the value of x? i.e. y = SplineFit["data.dat",Cubic] how to get y(x) with x being the value of variable instead of the order of the data points. regards,
