Solution 34505: Purpose of the GarbageCollect Function on the TI-84 Plus C Silver Edition Graphing Calculator.
What does the GarbageCollect function do on the TI-84 Plus C Silver Edition?
The GarbageCollect function on the TI-84 Plus C Silver Edition allows the cleanup of unused archive memory. It deletes unarchived variables from the user data archive and it rearranges the remaining variables into consecutive blocks. When a variable is unarchived, the amount of free Archive memory increases immediately, but the space is not actually available until after the next garbage collection.
To use the GarbageCollect function, follow the steps below:
• Press [2ND] [CATALOG].
• Press [G] to "jump" to section of commands starting with G.
• Press [ENTER] to paste the GargageCollect function onto the home screen.
• Press [ENTER] to display the Garbage Collect prompt.
• Press  to begin garbage collection.
