3-158 Full Command and Function Reference
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.

Type: Command
Description: Number of X-Steps Command: Sets the number of x-steps for each y-step in 3D perspective
plots.
The number of x-steps 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.

Description: Number of Y-Steps Command: Sets the number of y-steps across the view volume in 3D
perspective plots.
The number of y-steps is the number of dependent variable points plotted across the view
volume. This number must be 2 or more. This value is stored in the reserved variable VPAR.

OBJ→
Type: Command
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 top-level (least-nested) function (arg
1
… arg
n
), the number of arguments of the top-level function (n), and the name of the top-level
function (function).
If the argument is a string, the object sequence defined by the string is executed.
