Lesson 1:

Memory Management.

As you build programs, you will eventually want to learn how to arhive or delete the files. This is done through the Memory Menu. To access the Memory Menu, press [2nd] and [+]. You will be presented with a list of options.


About gives you the Operating System Version you have. It also gives Product # and ID #, which is useful only to Texas Intruments.

Mem Mgmt/Del...

Select this option to access Variables (Real, Complex, List, Matrix, Y-Vars, Pic, GDB, Strings, and appvars), programs, applications, and group files. To delete a file, scroll to it, then press [DEL]. To archive and unarchive a file, press [ENTER] when you have the cursor next to the file name. You cannot unarchive Applications. Clear Entries
Clear Entries can be run from either the Homescreen, or a program, and all it simply does is erase all of the items that are stored in the ENTRY portion of the memory. Beyond that, it is not overly useful.


This can also be run from either the homescreen or a program. What this does is set the dimension of each list to 0; it does not delete the list names.


There are 2 ways of using this command. If pasted on the homescreen, you can archive any type of variable and program. If you use this command inside of a program, you can only archive variables, like the list, matrice, strings, pics, etc. You CANNOT archive a program, within a program. This file takes a file in RAM and puts it into flash ROM.


This command follows the same guidelines as the Archive command, except it unarchives the files from flash ROM back to RAM.


This command allows you to reset either RAM, flash ROM, or all. Once this has been done, it cannot be undone.


To Group a file, it must be in RAM. You can Group any type of file/variable, as long as it resides in RAM. In this menu, you can either create a new Group file, or extract files from a group file back into RAM.

This concludes lesson 1, which shows you what is in your calculator's memory, and how to access it. In the next lesson, you will begin to learn the basics of TI-BASIC.
