The Letter v2.3 features: - Capital and small letters - Numbers - All special chars available on TI-83 like @ & # ~ \ % and many more - Fast delete, one line and total clear - Saving and opening as many files as you want - Deleting files - Changing contrast showing the contrast indicator - Very nice interface both on the main screen and save/open screen - Batteries friendly. How to use: 1. Send letter.83g to your calculator. Choose overwrite if asked. Start prgmLETTER. 2. You will see the Letter logo for couple of seconds. You can also skip it pressing ENTER. 3. You are coming to the home screen with a little prompt in the upper left corner. Now you can write lower and upper case letters, numbers and other chars, delete it, save and open files. - Choose case pressing the Y= key. - Press and hold left or right arrow to choose spec. char. - Type it pressing the WINDOW key. - Change contrast pressing UP or DOWN key. - Save your files pressing the ZOOM key. You will be prompted to SAVE screen. - Type the name of file and press ENTER. File is saved now. - Open your files pressing the TRACE key. You will be prompted to LOAD screen. - Choose the file you want to load pressing the right ARROW and press ENTER. File is loaded now. - Delete a file pressing the Y= key on the LOAD screen. - Exit the LOAD screen without loading pressing the GRAPH key. For more information about keys used in the program refer to UserGuide.htm 4. Quit pressing the GRAPH key. The Letter v2.3 uses TI-83:s home screen in format 16x8. Write important stuff (formulas, tel. numbers, addresses, or anything else), save it and open whenever you need it. Files you save are protected and can be found only by the Letter v2.3 or by TI-83 OS memory delete option. Note that the Letter v2.3 is not written to help you cheat. Its purpose is to remind. :) Saved files are saved like any usual program on TI-83 and take 133-138 bytes each depending on the file name. They get prefix 'let' in the name. So if you save a file and type TEST on the SAVE screen it's name will be letTEST. If you want to delete some file later you can do it like you would delete any other TI-83 program. You can delete files directly within the Letter v2.3 from the LOAD screen too. The Important Notes: !!!!Read this!!!! ASM program The Letter v2.3 is a TI-83 program written in assembly. There is always a risk executing an ASM code. You should "Back Up" all your important data before you start an ASM program. I am not responsible at any way if this program causes your calculator to crash and lose memory. Anyway it's been tested carefully and there shouldn't be any bugs at all. If you find any bug, have any suggestions, critics, comments, ideas, questions or anything else please mail me at saka@hotmail.com About Letter v2.3: The Letter v2.3 is programmed by Emir Sakic, it is Free Ware and may be copied freely.

The Letter.zip consists of the following files: letter.83g The program group for TI-OS. readme.txt This file. UserGuide.htm Users manual. Pictures Images used in the Users Guide. History: -10.12.2000. v2.3 for TI-OS, AShell and SOS This version (TI-OS). Searching routine improved and file format changed. Features contrast changing, deleting files and exiting the LOAD screen. Better batteries saving. Size: 1636 bytes. -17.06.2000. v2.2 for TI-83+ MirageOS Same as v2.1 for ION but assembled especially for MirageOS including a program icon. MirageOS hotkey combinations available. Size: 1315 bytes. -16.09.2000. v2.1 for ION ION compatible both for TI-83 and TI-83+. Uses ION built-in routine to search for program files. Program size now: TI-83 version: 1279, TI-83+ version: 1286 bytes -26.03.2000. v2.0 for SOS Version name dumped to 2.0 because it now uses a totally different way for writing and saving files. Program size is now only 1295 bytes. -10.01.1999. v1.0 First version. Size 3526 bytes. Big and unpractical. Could save only one file. Future versions: 1. Scrolling screen support. Files will not be limited at 111 chars and you will be able to scroll text up and down and save file with any size you want. 2. Improved input routine that would allow prompt back without deleting. 3. You tell me. :) Thanx to: -Dan Englender and Kouri Rosenberg for their help on previous versions. -Nathan Minor for revising the html help file.
