Lowercase support for TI-83 Plus
--------------------------------

This pair of assembly programs allows you to type in lowercase letters on the TI-83 Plus.
Note: these letters cannot function as variables, only as letters in strings.

To enable: Asm(prgmLWRON
To disable: Asm(prgmLWROFF


When enabled, ALPHA key functions as follows:
Alpha: [ALPHA]
Lowercase [ALPHA][ALPHA]
Alpha-lock: [ALPHA][2nd][ALPHA]
Lowercase lock: [2nd][ALPHA]
(when in Alpha lock)
[ALPHA]-go to lower case lock
(when in Lower case lock)
[ALPHA]-disable

NOTE! Alpha-lock and Lower-case lock are NOT reversed!!
[2nd][ALPHA] goes to LOWER CASE lock. Pressing ALPH

In case you're wondering, to enable this lower case support, the assembly code is:

#include "ti83plus.inc"
set lwrCaseEnable, (iy+appLowerCaseFlag) ; this only works on TI-83 Plus!
ret ; that's the whole program!


To disable it, change 'set' to 'res'.


NOTE!! I am not responsible for any damage that this causes to your calculator, computer,
or anything else!! USE AT YOUR OWN RISK!! I have tested this on a TI-83 Plus version 1.12.
PLEASE back up your calculator before use! If something does go wrong, you can restore it.
