How to Open and Delete Files in Cabri Jr. on the TI-84 Plus

By C. C. Edwards

To open a Cabri Jr. file previously saved in memory on the TI-84 Plus graphing calculator, press [Y=][5] to select Open from the F1 menu. Repeatedly press


to highlight the file you want to open and then press [ENTER] to open it. If the previous work on the screen was not saved, the calculator gives you the option of saving it before opening the requested file.

If you select Open from the F1 menu and then change your mind about opening an existing file, press [CLEAR] to get out of the dialog box without selecting a file.

To delete a Cabri Jr. file from the memory of the calculator, follow these steps:

  1. Press [2nd][+][2] to enter the Memory manager.

  2. Repeatedly press


    until the cursor is to the left of AppVars and press [ENTER].

    AppVars can also be selected by simply pressing [ALPHA][x–1].

  3. Repeatedly press


    until the cursor is to the left of the file you want to delete and press [DEL].

  4. Press [2] if you really want to delete the file; press [1] if you chicken out about deleting the file from memory.
