TI-83 Plus Memory and Variable Management 628
ERR:ARCHIVE FULL Message
Even if the MEMORY screen shows enough free
space to archive a variable or store an
application, you may still get an
ERR: ARCHIVE
FULL message.
An ERR:ARCHIVE FULL message may be displayed:
•
When there is insufficient space to archive a variable within a
continuous block and within a single sector.
•
When there is insufficient space to store an application within a
continuous block of memory.
When the message is displayed, it will indicate the largest single space
of memory available for storing a variable and an application.
To resolve the problem, use the GarbageCollect command to optimize
memory. If memory is still insufficient, you must delete variables or
applications to increase space.
