TI-83 Plus Memory and Variable Management 626
If the MEMORY Screen Shows Enough Free Space
Even if the MEMORY screen shows enough free space to archive a
variable or store an application, you may still get a Garbage Collect?
message or an ERR: ARCHIVE FULL message.
When you unarchive a variable, the Archive free amount increases
immediately, but the space is not actually available until after the next
garbage collection.
If the Archive free amount shows enough available space for your
variable, there probably will be enough space to archive it after garbage
collection (depending on the usability of any empty blocks).
The Garbage Collection Process
The garbage collection process:
•
Deletes unarchived variables from
the user data archive.
•
Rearranges the remaining
variables into consecutive blocks.
Note: Power loss during garbage collection may cause all memory (RAM and
Archive) to be deleted.
