Item Description
Expr
Input the function expression
f
(
x
) for generating the number sequence.
Example: ? (X) V @ U (X 2 + 1)
Var Input the variable name used in the function expression input for Expr.
Example:
?
(X)
U
(X)
Start Input the starting value (X
1
) of the value to be substituted for the variable
specified by Var.
Example:
A U
End Input the ending value (X
n
) of the value to be substituted for the variable
specified by Var.
Example: @? U
Incre
Input the increment value (
m
) for successive value of X
1
, as in: (X
2
= X
1
+
m
),
(X
3
= X
2
+
m
), and so on. The number sequence is generated in the range of
X
1
+ (
n
– 1)
m
X
n
.
Example: A U
1st Cell Input the reference name (A1, B2, etc.) of the cell where you want the first
value of the number sequence to be input. Specify a cell here only if the
starting cell is different from the one you specified in step 1 of this procedure.
Example:
?J
(B)
@ U
(B1)
• Each time you press
U
after inputting data for a setting item, the highlighting will move to
the next setting item. You also can use D and A to move the highlighting upwards and
downwards as required.
• Performing the next step will input the number string automatically starting from the
specified cell. If any cell that is within the range of cells where the number sequence
values will be input already contains data, the existing data will be replaced with the
number sequence values.
3. After inputting data for all the setting items, press (EXE) or the U key to start number
sequence generation and input.
