You know, if you can't get to the ram clear menu or are unable to clear your ram for some reason where taking out the batteries doesn't work, you can always take out the backup battery (which powers the ram) to guarantee a ram clear even if the calculator wasn't frozen.
For 1 minute, I assume, right? Because I removed all 5 batteries once, then immediately put them back, yet my RAM was still intact.

Hmm, that's weird.  Were you on the homescreen when you pulled the batteries?  Because pulling the batteries while on the home screen doesn't cause a RAM clear -- you have to be running a program or something.
Even when removing the lithium one too? And yeah I was on the home screen.

Well...
I don't know about the lithium -- I've never had a reason to take it out, so I've no clue as to what would happen.

Okay, So I was thinking about Movement programs, and I was wondering. I made a program That went like this.

.Movement
[FFFFFFFFFFFFFFFF->pic1
20->X
20->Y
Repeat getkey(54)
Pt-change(X,Y,pic1
dispgraph
Pt-change(X,Y,pic1
X+(Getkey(4) and X=/= edge )-(getkey(1) and x=/=1) -> X
Y+(getkey(3) and Y=/= Edge)-(getkey(2) and Y=/=1)-> Y
End.

When it displayed it, it displayed it at 20 20, then moved it to like 1, 6. When I tried to move the dot, it would move one space, and then go back to 1,6. Any idea what i am doing wrong?

You can't use it like  "getKey(1) and X!=1" That will evaluate like "(getKey(1) and X)!=1", which is not what you want.
To get the correct order of operations, you either need to put parentheses around (X!=1) or else change the order to "X!=1 and getKey(1)"
Note: This goes for all of them, not just the part with getKey(1) ;)
