HP 50g Graphing, 48gII Graphing manual Numx, Numy, Obj→

The number of a character can be found by accessing the Characters tool (…±) and highlighting that character. The number appears near the bottom of the screen. These are also listed in Appendix J of this manual.

Access:	!°TYPE LNUM		( °is the leftshift of the		Nkey).
	!°LCHARS NUM		( °is the leftshift of the		Nkey).

NUMX	Command
Type:
Description:	Number of XSteps Command: Sets the number of			xsteps for each		ystep in 3D perspective
	plots.
	The number of xsteps is the number of independent variable points					plotted for each dependent
	variable point plotted. This number must be 2 or more. This value is stored in the reserved
	variable VPAR. YSLICE is the only 3D plot type that does not use this value.

NUMY	Command
Type:
Description:	Number of YSteps Command: Sets the number of			ysteps across the view volume in 3D
	perspective plots.
	The number of ysteps is the number of dependent v ariable points plotted across the view
	volume. This number must be 2 or more. This value is stored in the reserved variable VPAR.
Access:	…µNUMY

OBJ→	Command
Type:
Description:	Object to Stack Command: Separates an object into its components. For some object types, the
	number of components is returned as item n+1 (stack level 1).

If the argument is a complex number, list, array, or string, OBJ→ provides the same functions as C→R, LIST→, ARRY→, and STR→, respectively. For lists, OBJ→ also returns the number of list elements. If the argument is an array, OBJ→ also returns the dimensions { m n } of the array, where m is the number of rows and n is the number of columns.

For algebraic objects, OBJ→ returns the arguments of the toplevel (leastnested) function ( arg1

…argn), the number of arguments of the toplevel functio n (n), and the name of the toplevel function (function).

If the argument is a string, the object sequence defined by the string is executed.

Access: !°TYPE OBJ→ ( °is the leftshift of the Nkey).
