Press ¸ to replace the current contents of list L1. If you want to save the current contents of

Additional TI-89 Step
With these calculators, the lists will default to being named L1, L2, etc in the main folder.
They can be used (and accessed) with ° just like the default lists for graphs and other

0.10 Memory Management
Too many applications loaded or lists in active memory can overload the calculator. Just as a
computer disk can be filled up, so can memory on the calculator. The TI calculators have two
types of memory – RAM and archival. If you use the applications supplied on the CD (on a TI-
83/84), these are loaded into archival memory. Active lists are in RAM.
TI-83/84 Procedure
To find out the current free memory status, press yà (MEM) and
select option 2:Mem Mgmt/Del.
The screen at right shows my calculator currently has 18,927 bytes
(characters) of free RAM and 1303Kilobytes of free archival
memory.
If you need to free some memory, decide the type. If you want to
delete some lists, for example, select 4:List. Move the cursor to
the lists you wish to delete and press { for each one. The can also
be done for any applications you no longer need from previous
chapters, but use choice 5:Archive to access the list of archived
applications.
TI-89 Series Procedure
To find out the current free memory status, press 2{. The screen
at right shows I currently have 194,232 free bytes of RAM and
338096 free bytes of Flash memory free. Pressing ƒ here will reset
