List Function
A list is a kind of container that you can use to store multiple data
items.
This calculator lets you store up to six lists in a single file, and
you can store up to six files in memory. Stored lists can be used
in arithmetic, statistical, and matrix calculations, and for graphing.

17-1 List Operations
Select the LIST icon in the Main Menu and enter the LIST Mode to input data into
a list and to manipulate list data.
uu
uu
uTo input values one-by-one
Use the cursor keys to move the highlighting to the list name or cell you want to
select. Note that cdoes not move the highlighting to a cell that does not contain
a value.
The screen automatically scrolls when the highlighting is located at either edge of
the screen.
The following example procedure is performed starting with the highlighting
located at Cell 1 of List 1.
1. Input a value and press wto store it in the list.
dw
2. The highlighting automatically moves down to the next cell for input.
• Note that you can also input the result of an expression in a cell. The following
operation shows how to input the value 4 in the second cell and then input the
result of 2 + 3 in the next cell.
ewc+dw

232
uu
uu
uTo batch input a series of values
1. Use the cursor keys to move the highlighting to another list.
2. Press !{, and then input the values you want, pressing ,between each
one. Press !}after inputting the final value.
!{g,h,i!}
3. Press wto store all of the values in your list.
w
• Remember that a comma separates values, so you should not input a
comma after the final value of the set you are inputting.
Right: {34, 53, 78}
Wrong: {34, 53, 78,}
You can also use list names inside of a mathematical expression to input values
into another cell. The following example shows how to add the values in each row
in List 1 and List 2, and input the result into List 3.
1. Use the cursor keys to move the highlighting to the name of the list where you
want the calculation results to be input.
2. Press Kand input the expression.

uTo change a cell value
Use dor eto move the highlighting to the cell whose value you want to
change. Input the new value and press wto replace the old data with the new
one.

uTo delete a cell
1. Use the cursor keys to move the highlighting to the cell you want to delete.

3
2. Press 3(DEL) to delete the selected cell and cause everything below it to be
shifted up.
• Note that the above cell delete operation does not affect cells in other lists. If
the data in the list whose cell you delete is somehow related to the data in
neighboring lists, deleting a cell can cause related values to become
misaligned.
uu
uu
uTo delete all cells in a list
Use the following procedure to delete all the data in a list.
1. Use the cursor key to move the highlighting to any cell of the list whose data
you want to delete.
2. Press 4(DEL-A). The function menu changes to confirm whether you really
want to delete all the cells in the list.
3. Press 1(YES) to delete all the cells in the selected list or 6(NO) to abort
the delete operation without deleting anything.

234
uu
uu
uTo insert a new cell
1. Use the cursor keys to move the highlighting to the location where you want to
insert the new cell.
2. Press 5(INS) to insert a new cell, which contains a value of 0, causing
everything below it to be shifted down.
• Note that the above cell insert operation does not affect cells in other lists. If
the data in the list where you insert a cell is somehow related to the data in
neighboring lists, inserting a cell can cause related values to become
misaligned.

kSorting List Values
You can sort lists into either ascending or descending order. The highlighting can
be located in any cell of the list.
uu
uu
uTo sort a single list
Ascending order
1. While the lists are on the screen, press 1(SRT-A).
2. The prompt “How Many Lists? (H)” appears to ask how many lists you want to
sort. Here we will input 1 to indicate we want to sort only one list.

3. In response to the “Select List (L)” prompt, input the number of the list you want
to sort. Here we will input 2 to specify sorting of List 2.
cw
Descending order
Use the same procedure as that for the ascending order sort. The only difference
is that you should press 2(SRT-D) in place of 1(SRT-A).
uu
uu
uTo sort multiple lists
You can link multiple lists together for a sort so that all of their cells are rearranged
in accordance with the sorting of a base list. The base list is sorted into either
ascending order or descending order, while the cells of the linked lists are
arranged so that the relative relationship of all the rows is maintained.
Ascending order
1. While the lists are on the screen, press 1(SRT-A).
2. The prompt “How Many Lists? (H)” appears to ask how many lists you want to
sort. Here we will sort one base list linked to one other list, so we should input 2.
cw
3. In response to the “Select Base List (B)” prompt, input the number of the list
you want to sort into ascending order. Here we will specify List 1.
bw
4. In response to the “Select Second List (L)” prompt, input the number of the list
you want to link to the base list. Here we will specify List 2.
cw

Descending order
Use the same procedure as that for the ascending order sort. The only difference
is that you should press 2(SRT-D) in place of 1(SRT-A).
• You can sort up to six lists at one time.
• If you specify a list more than once for a single sort operation, an error occurs.
An error also occurs if lists specified for sorting do not have the same number of
values (rows).

17-3 Manipulating List Data
List data can be used in arithmetic and function calculations. In addition, various
list data manipulation functions makes manipulation of list data quick and easy.
You can use list data manipulation functions in the RUN,STAT,MAT,LIST,
TABLE,EQUA and PRGM Modes.

kAccessing the List Data Manipulation Function Menu
All of the following examples are performed after entering the RUN Mode.
Press Kand then 1(LIST) to display the list data manipulation menu, which
contains the following items.
•{List}/{L→M}/{Dim}/{Fill}/{Seq}/{Min}/{Max}/{Mean}/{Med}/{Sum}/{Prod}/
{Cuml}/{%}/{AA
