   |									       |
   | I decided to apply some of the tutorials of ASMGuru into a program.       |
   | So I made System Tool, which has multiple functions.		       | 									      |
   | The features are:		                                               |
   |  1) Set inversed text, to use in Basic; :)                                |
   |  2) System Info;							       |
   |	 - Check Free memory in ASM;                                           |
   |  	 - Check Battery Status (it will tell "OK", or "Low");                 |
   |  3) Change contrast;  						       |
   |  4) Protect all files on calc.	     				       |
   |									       |
   +============ Option1: Inversed Text =======================================+  
   |									       |
   | When you've selected inversed text, it will immediately affect the menu,  |
   | All text will change, but don't worry...nothing will be damaged.          |
   | When you exit Ion (with inversed text still selected) you will be able to |
   | use the inversed text in basic mode, but beware... the usage is limited.  |
   | When you select a menu and return, Inversed text will be undone, and text |
   | is back to normal. Normal calculations WILL be able to be done in inversed|
   | text. (If you don't understand, just try it out, nothing can go wrong!).  |
   |									       |
   +============ Option2: System Info =========================================+  
   |									       |
   | When you've selected System Info it will dispay the amount of free ram,   |
   | on the next line it will display if the battery's are OK or Low.          |
   | Press any key to return to the main menu.				       |
   |									       |
   +============ Option3: Contrast ============================================+  
   |									       |
   | With this options selected, you can change the contrast, use the left     |
   | and right key to change it. An extra here is when your batteries are low  |
   | you can set the contrast to max and it will be darker than when you set   |
   | max contrast in basic! This is handy because you can now use your         |
   | batteries a little longer. Press clear to return to main menu.	       |
   |									       |
   +============ Option4: Protect *.* =========================================+  
   |									       |
   | This option will protect all programs on your calc in a sec. In the       |
   | future you'll be able to protect them individualy.                        |
   |									       |
   +============ Future plans =================================================+  
   |									       |
   | I'm still learning a lot, so there's still a lot to come:		       |
   | - (Un)Protecting individual programs;                                     |  
   | - Hiding programs;							       |  
   | - MMM...mail me if you know more! (magicNBA@hotmail.com)		       |
   |									       |
   |   You may edit the credits part of the prgm away, I don't mind that.      |   
   |   The main reason for distributing this file is to let people see	       |
   |   how to prgm in assembly. (After you've edited it DONT REDISTRIBUTE).    |
