=== Lists and loops ===

==== TI-83/84 (Z80 Series) ====
<pre>
PROGRAM:LISTS
:"ASK FOR THE NUMBER OF VARIABLES
:Input "NUMBER OF VARS? ",A
:"VALIDATE INPUT OR STOP
:If A<1 or fPart(A)
:Stop
:"A FOR LOOP TO ASK FOR EACH VALUE TO BE IN THE LIST
:For(N,1,A)
:Input "VAR ",B
:"STORE THE VALUE INTO THE NTH ELEMENT
:B→L1(N)
:End
:"IMPLICITLY RETURN THE FINAL LIST
:L1
</pre>

==== TI-89 (68k Series) ====
<pre>
lists()
:Prgm
:  Local n,i,c © Declare local variables n, i, and c.
:  {}→list © Initialize list as an empty list.
:  Input "Number of variables?",n 
:  For i,1,n
:    Input "Variable #"&string(i),c © & concatenates i after it is converted to a string.
:    c→list[i]
:  EndFor
:EndPrgm
</pre>

Lists have many possible names, this allows for many programs to manipulate many lists without overriding previous data. Lists on the TI-82 cannot have custom names (L<sub>1</sub> through L<sub>6</sub> are preprogrammed). The TI-85 and TI-86 do not have the ability to handle a variable name with subscripts. The TI-81 is completely unable to handle lists. Lists can be used by the numerous built-in TI-BASIC functions for calculating statistics, including various [[Regression analysis|regression analyses]] and [https://education.ti.com/en/guidebook/details/en/123AB1F6CF524A188FCDDF107041A019/83 more].<ref name=":0" /> These can be called inside of programs, however they still show the info while pausing execution and they cannot store specific results into variables.
