Attach List Formula
Description
… (
List) Æ 4:Attach List Formula
Attach List Formula attaches a formula to a specified list so that each list element is a
result of the formula, which resolves to a list when executed.
Example
Setup: list1={1,2,3,4,5,6}
1. Highlight the list (
list2) to which you want to attach a formula.
2. Press … (List) and select 4:Attach List Formula. Enter the formula (list1 + 10) and the
formula name (
zlist2) as shown below.
Tip: You can press 2 °, highlight a list,
and then press ¸ to paste the list name into
the list editor. Be sure to close arguments with a
right parenthesis (d).
You can also press … (List) and select 1:Names
to display the VAR-LINK [All] menu.
3. Press ¸ to display the list.
You can create list2 using list1+10, but without attaching the formula.
1. With list2 name highlighted, enter the formula in the entry line (list2=list1+10).
2. Press ¸. The elements in list2 are updated.
The formula is not attached to list2; therefore, list2 is updated using list1+10 when you
press ¸, but
list2 will not be updated whenever list1 is updated.
Note: In this case, the formula will not be in quotation marks in the entry line, and the lock symbol
(é) will not display next to list2.
For more information about attaching a formula to a list, see Formulas in the List
chapter.
The square symbol next to the list
name means that the formula is
attached. If list1 changes, list2 is
updated.
