1	FIT

	This program will take as input the name of a standard X-Y
	data file containing data in the form 
 
		2 control bytes, 70 title bytes
		I*2, Real*4, Real*4
		...  ...     ...
		I*2, Real*4, Real*4
		I*2, Real*4, Real*4

	and fit the data (up to Max_Points (600 points or so)) to one of

     		Exponential function  Y=AExp(BX)
     		Linear Polynomial     Y=A+BX+CX**2+DX**3....
     		Power function        Y=AX**B

	If the fit is to a polynomial,  the user must input the degree 
	of the polynomial.  The program then displays the curve fitting 
	parameters and plots the input data with the fitted curve (number 
	of points displayed on fitted curve is selectable) and optionally 
	output a new data file containing the output data from the curve fit.

	CURVE_FIT is accessed either from the Graph Master VPW menu or by
	running SYS$VPWFILES:CURVFIT.
