Ah I see. Well I guess it's best to have it disabled by a patch (or add a secret backdoor to disable it in case the teacher notices) in case teachers won't bother turning it off after tests. I wish TI found a different way to disable it...

The USB activity hook persists as well. They're very clumsy and just wipe out iy+34h/35h/36h (or whichever the 3 hook flags are, I forget), but not iy+3Ah which is where the USB activity hook's active flag is.

So you could carry around a USB adapter and jam it into the port whenever you want to re-enable it (after installing a USB activity hook that calls _RemoveAppRestrictions and uninstalls itself).

Interesting.  Although of course, neither that, nor OFFSCRPT, would work after a RAM clear.

PTT does not clear RAM, though ;)

Do you mean the ←+→+ ON/8+5+ON combination?

Didn't even know about the 8+5 one. Is it basically a reset all?

It lets you reset apps/programs.

8+2+ON shows the same message, but says FOR SINGAPORE as well.

Really?  I knew about the left-right-ON one, but not the others.  This would be a good prank to pull on a calc programmer.  (Not that I would ever do such a thing)

Actually, it's quite horrible considering it deletes the groups. But assuming that person doesn't use groups, then sure. You could also hold clear on a ram clear, that will scare them.

Is there any difference, or is it still about the same clear? Why does TI add this Singapore stuff, anyway?

And thanks for all those fixes, thepenguin77! Is Mod253 basically most of them combined?

It doesn't delete the Singapore localization app, and perhaps a few others. This was probably added because some teachers in Singapore complained.

Mod253 is basically my calc modding program. I made it for me to use so that I could undo all of it with one program. But, I figure, why keep it all to myself. I haven't seen the standard ram clear screen for about 3 months now.

I wonder if teachers complains would be the same reason as why OS 2.43 is still available on the Singapore TI page (as well as 2.53MP) but not anywhere else?

Yeah, that.
But they spelled singapore wrong, they spell it Signapore.  Another example of TI's brilliance.

Nice :D
Actually, are int( and iPart( only different for negative numbers? int( is the command I use for parser hooks (I have never released a program using the parser hook yet, but I make them every now and again for fun and for friends), so I was curious about how that might affect programmers if I ever did release one...

I've never used ipart(), for some reason I've always used int().
So, it would mess me up. ;D
