XXRNG	Command
Type:
Description:	X Range of an Input Plane (Domain) Command: Specifies the x range of an input plane (domain)
	for GRIDMAP and PARSURFACE plots.

xmin and xmax are real numbers that set the xcoordinates for th e input plane. These values are stored in the reserved variable VPAR.

ΣXY	Command
Type:
Description:	Sum of X times Y command: Sums the products of each of the corresponding values in the
	independent and dependentvariable columns of the			current statistical matrix (reserved variable
	ΣDAT). The independent column is the column designated as XCOL and the dependent column
	is the column designated as YCOL.
Access:	…µΣXY
Input/Output:
		Level 1/Argument 1			Level 1/Item 1
				→	Sum of X*Y

ΣX*Y	Command
Type:

Description: Sum of X times Y command: Sums the products of each of the corresponding values in the independent and dependentvariable columns of the current statistical matrix. ΣX*Y is provided for compatibility with the HP 28. ΣX*Y is the same as ΣXY; see its listing for details.
