Memory and Variable Management 693
If a Garbage Collection Message Is Displayed
If you use the user data archive extensively, you may see a Garbage Collection
message. This occurs if you try to archive a variable when there is not enough free
archive memory. However, the TI-89 Titanium will attempt to rearrange the archived
variables to make additional room.
Responding to the Garbage Collection Message
After garbage collection, depending on how much additional space is freed, the variable
may or may not be archived. If not, you can unarchive some variables and try again.
Why not Perform Garbage Collection Automatically, without a
Message?
The message:
• Lets you know why an archive will take longer than usual. It also alerts you that the
archive may fail if there is not enough memory.
• Can alert you when a program is caught in a loop that repetitively fills the user data
archive. Cancel the archive and investigate the reason.
When you see the message to the right:
• To continue archiving, press ¸.
– or –
• To cancel, press N.
