Texas Instruments TI-89 Titanium Short User Manual

146 Memory and Variable Management
Unarchived variables are “marked for deletion,” meaning they will be
deleted during the next garbage collection.
If the MEMORY Screen Shows Enough Free Space
Even if the MEMORY screen shows enough free space to archive a
variable, you may still get a Garbage Collection message.
The Garbage Collection Process
The garbage collection process:
• Deletes unarchived variables from the user data archive.
• Rearranges the remaining variables into consecutive blocks.
This TI-89 Titanium memory screen shows free
space that will be available after all “marked for
deletion” variables are deleted.
When you unarchive a variable, the Flash ROM
free amount increases immediately, but the
space is not actually available until after the
next garbage collection.
variable A
variable D
After you unarchive
variables B and C, they
continue to take up space.
