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.

Command

 

 

Type:

 

 

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.

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 top-level (least-nested) function (arg1

…argn), 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.
