    |									        |
    | 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;			                        |
    |  3) Change contrast (Higher Max than Basic Max); 			        |
    |  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 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).    |
