Step?
Input the increment step (Default = 1).
Note: The Step specifies by how
much the Start value should be
sequentially incremented as the
numerical table is generated. If you
specify Start = 1 and Step = 1, X
sequentially will be assigned the
values 1, 2, 3, 4, and so on to
generate the numerical table until the
End value is reached.
Inputting the Step value and pressing generates and displays the
numerical table in accordance with the parameters you specified.
Pressing while the numerical table screen is displayed will return
to the function input screen in step 2.
Example: To generate a numerical table for the functions f(x) = x

the range -1 x 1, incremented in steps of 0.5 (MthIO-MathO)

Note
You can use the numerical table screen for viewing values only. Table contents
cannot be edited.
The numerical table generation operation causes the contents of variable X to be
changed.
The specified Start, End, and Step values should produce a maximum of 30 X-
values for the numerical table being generated. Executing a numerical table
generation using a Start, End, and Step value combination that produces more than
30 X-values causes an error.
