JP Glitch

Luckily, it is quite simple, and hardly time consuming.(unless you concider pressing buttons on the controller for about two minutes a waste of time? -and if you do, then you are a blasphemous square player and should not even be playing the game.) It goes a little something like this:

• Get a character who has access to one of the job classes that are mentioned in the "What Will Work" section.
• On the world map, hit Triangle to bring up the main menu. Select Formation, select your character, go to Ability, then to Learn. Select any class from the "What WILL Work" section and go to an unlearned ability that you have enough JP to learn. We will call this ability 'Ability X'.
• Hit circle on Ability X and a Dialog Box will come up saying, "Is 'Ability X', OK?" Do not select YES yet!
• Hold square. Now, press down or up on the control pad. What's this?! The cursor is no longer pointing to Ability X, but the dialog box is still there, patiently waiting for you to confirm or deny it the right to spend your hard earned JP.
• You have successfully "page down"ed (or "page up"ed). And here's the trick:
   - If the ability the cursor is now pointing to:
   -   a) costs more JP than you currently have (it is dimmed out)
   -   OR
   -   b) it has already been learned
  ... choose Yes.
  
  

Each time you glitch a certain ability, the same amount lossed/gained always occurs. The effects are charted below.

- When you gain/lose JP with this glitch, your Job Level doesn't change.

Symbol	Description
O	JP goes to 0000, but all the abilities are immediately available to learn. If you don't learn all abilities and exit from the menu, when you come back you will have 9999 JP available.
o	JP goes to 0000, and none of the abilities are immediately available to learn. (Interestingly, you can't even learn the Chemist Ability "Equip Change," which costs 0 JP.) HOWEVER, when you exit the menu and come back, you have 9999 JP available to spend.
+	You gain JP (the number next to it is how much you gain)
-	You lose JP (the number next to it is how much you lose)
X	Nothing happens at all.
?	No idea. Either it can't be done or I haven't found a way to do it

The charts are composed of three columns: Ability, UL, and L. The Ability column contains, obviously, the name of each ability in the class. The L column displays the effect of the glitch if the respective ability has already been learned, and the UL column displays the effect of the glitch if the ability is un-leanred - it has not yet been learned.
