How to Group and Ungroup Programs on the TI-84 Plus

You can group variables residing in RAM memory and store the group in archive memory of your TI-84 Plus for safekeeping. Then, if the RAM on your calculator is cleared, you can ungroup the variables and they will be restored in their original state. It's a great idea to group the programs stored in the RAM of your calculator.

Here are the steps to group and ungroup programs:

  1. Press [2nd][+][8] to access the GROUP UNGROUP menu.

    See the first screen.

  2. Press [ENTER] to create a new group.

  3. Enter a name for the group and press [ENTER].

    See the second and third screens.

  4. Pressing [3] enables you to select programs from a list.

  5. Use the up- and down-arrow keys and press [ENTER] to select programs you wish to group.

    Notice the small square next to the programs you have selected. See the first screen.

  6. To select DONE, press


    You have successfully created a group of programs. If the RAM on your calculator is cleared, you now have a backup of your programs. See the second screen.

  7. To ungroup, press


    to see a list of groups. See the third screen. Ungrouping will not delete the original group. The group remains in archived memory until you decide to delete the group.

  8. Use the up- and down-arrow keys and press [ENTER] to select the group you wish to ungroup.

    If you ungroup a program that already exists in the RAM, you will be given the option to rename or overwrite the program.
